26-Year-Old CenterC
Oklahoma City Thunder
2024 Fantasy Outlook
After years of frustration, Hartenstein realized his potential during the 2023-24 season, putting together a career-best campaign. Despite starting the year as the backup behind Mitchell Robinson, Hartenstein started more games than ever thanks to a significant injury to Robinson. Hartenstein ended with averages of 7.8 points, 8.3 rebounds, 2.5 assists, 1.2 steals and 1.1 blocks in 25.3 minutes per game, good enough for top-75 value. Following his breakout, Hartenstein was signed by the Thunder, a team desperately in need of a big body to play either behind or alongside Chet Holmgren. While his role is a little unclear, it's safe to assume that Hartenstein should see upwards of 25 minutes per game once again. While his ceiling remains capped as long as Holmgren is healthy, there is no reason to think Hartenstein can't flirt with top-100 value. If Oklahoma City decides to start Hartenstein next to Holmgren at any point, the former's short-term value could see a small bump. No matter his assigned role, Hartenstein makes for a viable late-round target, even more so for anyone punting points. Read Past Outlooks

Personal Bio/PreCareer Summary

Isaiah Hartenstein was born in Eugene, Oregon, to Florian (Flo) and Theresa Hartenstein. His father played basketball at the University of Oregon and professionally in Germany. That led the Hartenstein family to move to Germany in 2008. Isaiah Hartenstein later spent four seasons playing in Germany's youth and boys divisions from 2011-12 through 2014-15. He represented Germany in three FIBA events at the U16 and U18 levels, averaging 12.2 points and 9.1 rebounds per game. In 2016, he took part in the NBA's Basketball Without Borders camp. Learn more about Hartenstein by following him on Twitter and on Instagram (@Ipjh55). The Geman-born Hartenstein followed his father into basketball. He first appeared for the Artland Dragons' junior team and was the MVP of the Under-16 Bundesliga JBBL. The seven-footer posted 20.9 points, 12.1 rebounds, 3.4 assists, 2.9 steals and 1.9 blocks. He played in the 2014 Jordan Brand Classic and put up four points and five rebounds across 18 minutes. He played for the Dragons again in 2015-16 and provided 11.5 points, 8.9 rebounds and 2.1 blocks. The center moved to Zalgiris Kaunas in Lithuania and helped the team win the King Mindaugas Cup for the first time in franchise history. He played in the 2017 Nike Hoop Summit and provided 10 points and three rebounds. He then declared for the 2017 NBA Draft. He was selected with the 43rd overall pick in the 2017 NBA Draft by the Houston Rockets.

Bound for OKC on three-year deal
COklahoma City Thunder
July 1, 2024
Hartenstein agreed with the Thunder on a three-year, $87 million contract Monday, Shams Charania of The Athletic reports.
ANALYSIS
Hartenstein had a massive market heading into free agency, so the Thunder had to act quickly to secure his services. Frontcourt depth was an obvious weakness for the Thunder last season, so adding Hartenstein will make Oklahoma City an even more formidable threat in the Western Conference. During the 2023-24 campaign with the Knicks, Hartenstein produced averages of 7.8 points, 8.3 rebounds, 2.5 assists, 1.2 steals and 1.1 blocks in 25.3 minutes per contest over 75 regular-season appearances. Assuming the Thunder choose to deploy Hartenstein as their starting center, Chet Holmgren and Jalen Williams will likely slide to power forward and small forward, respectively, while one of Luguentz Dort or Alex Caruso would head to the bench.

2018
Hartenstein has been a per-minute stud throughout his career, but that didn't carry over into last season. The big man averaged 5.0 points, 6.5 rebounds, 1.2 assists, 0.6 steals and 0.8 blocks on 53.5 percent shooting across nearly 20 minutes a night. Most of those numbers are fantastic for a 20-minute player, but scoring just five points per game is unusual from such a talented big man. The reduced efficiency is the primary reason for the fall off, with Hartenstein shooting 61 percent in the three previous years. He also had plenty of chances to take on a bigger workload when Julius Randle and Mitchell Robinson were sidelined, but his averages weren't any different in his eight games as a starter. The big man fills every stat that you want to see in fantasy basketball, but it really doesn't matter in a role like this. Being stuck behind minute hounds like Randle and Robinson is rough for Hartenstein's fantasy value, especially since Jericho Sims and Isaiah Roby are also in the picture. It would take a ton of injuries for Hartenstein to become a fantasy-relevant option, but he's always a sneaky stream or DFS target whenever one of those big men has to sit.
Despite playing just 17.9 minutes per game with the Clippers last season, Hartenstein was a fringe standard league option at center - a position of scarcity. His numbers excellently translate to fantasy, and he ranked 148th in per-game production behind 8.3 points on 62.6 percent shooting, 4.9 rebounds, 2.4 assists and 1.8 combined blocks-plus-steals. The 24-year-old big man also shot an acceptable 68.9 percent from the charity stripe on 1.9 attempts per game. He signed a contract with the Knicks this season, where he'll presumably claim the backup job behind Mitchell Robinson. That said, Robinson has never played more than 27.5 minutes per game in a season, so he and Hartenstein may end up more in a time split. If Hartenstein continues having a similar usage level as he did on the Clippers, he could fall in fantasy sleeper territory this season. When seeing minutes in the 20s last year, the center averaged 11.3 points, 6.4 rebounds, 3.9 assists and 2.3 combined blocks-plus-steals - sizable numbers that would certainly hold standard-league relevance. Managers in standard leagues may have an opportunity to grab him off the waiver wire at some point, but he should be a staple as a draft-day flier in deeper leagues and best ball formats.
Hartenstein is expected to compete with Paul Millsap and rookie Zeke Nnaji for the top backup role at center behind superstar Nikola Jokic. Over his 23 appearances with the Rockets in 2019-20, Hartenstein was one of the league's stronger producers on a per-minute basis. He averaged 4.7 points, 3.9 rebounds, 0.8 assists, 0.5 blocks and 0.4 steals in 11.6 minutes of run while converting at a 65.7 percent clip from the field. However, given the 22-year-old's expected role this season, he can largely be passed on from a fantasy standpoint.
A second-round pick in 2017, Hartenstein mostly toiled in the G League over his first two professional seasons. The seven-footer averaged 9.5 points and 6.5 rebounds over 38 games for Rio Grande during the 2017-18 campaign before putting up 19.5 points, 14.7 rebounds, 3.8 assists and 2.0 blocks across 32.3 minutes over 26 games for the Vipers last season. Hartenstein also got his first taste of action at the NBA level, appearing in another 28 games for the Rockets during 2018-19 and parlaying a modest 7.9 minutes per contest into averages of 1.9 points and 1.7 rebounds (28 games). Hartenstein then continued his development in the Las Vegas Summer League and was on his way to a stellar showing by putting 16.0 points, 8.7 rebounds, 1.7 blocks and 1.7 steals over his first three games in the desert before a right ankle injury shut him down. As that collection of numbers indicates, Hartenstein has essentially demonstrated improvement on each occasion that he's been given extended playing time, which bodes well for his future prospects. However, in Houston, his path to meaningful playing time to open the new season is blocked by Clint Capela at the top of the center depth chart, along with a pair of grizzled but still capable veterans in Tyson Chandler and Nene Hilario behind him. Therefore, Hartenstein may be set for a modest allotment of playing time for a second straight season when it comes to the NBA level, although it's certainly possible he moves up a notch on the depth chart if Chandler proves to be expendable or experiences a notable downturn in his play during what will be his age-36 season.
Hartenstein was drafted by the Rockets in the second round of the 2017 draft, but spent last year in the G League, where he averaged 9.5 points, 6.6 rebounds and 1.2 assists in just under 19 minutes per game. The German native then joined the Rockets for summer league this July and came out of it with a guaranteed contract. He'll provide depth at both power forward and center, but will likely spend most of the year in a developmental capacity and will likely need multiple injuries to occur to become a relevant Fantasy player.

Latest Fantasy Rumors
Working on three-point shot
COklahoma City Thunder
August 17, 2024
Hartenstein has been working on his three-point shot during the offseason, Clemente Almanza of ThunderWire reports.
ANALYSIS
The 26-year-old big man is fresh off a career season with the Knicks in 2023-24, when he stepped up as the starter once Mitchell Robinson went down, and he figures to remain in a starting role for Oklahoma City in 2024-25, sliding Chet Holmgren to the power forward position. Hartenstein is looking to add another layer to his offensive game with his three-point shot, and if he succeeds, he could become a serious weapon for OKC while draining threes from the corner.
