Tyrese Haliburton’s trainer, Drew Hanlen, put former Milwaukee Bucks guard Brandon Jennings on blast ahead of the NBA Finals. It was Jennings who kicked off the entire thing after he called Hanlen out on X. The former NBA star came across an article that claimed that the trainer puts his players in “text chains” and talks trash to motivate them.He went on to say that Drew Hanlen is too “buddy-buddy” with his clients and compared him to Rob McClanaghan, who has worked with stars like Derrick Rose, Stephen Curry, Kevin Durant, Russell Westbrook and more.Brandon Jennings @Tuff__CrowdI’m reading this article on how Drew Hanlen puts his guys in “Text Chain” to tell them they won’t do this or this guy is better and etc. weird and stupid I said this earlier in the year to much buddy buddy when it comes to that guy.I’m sorry but Robmac would never have Drose,KD,Westbrook, Klove, and etc all in text chain saying who can’t win MVP!!!! GTFOH!!!!Jennings didn’t just stop here, making a separate tweet tagging Drew Hanlen and calling him out for being a “groupie trainer.” Brandon Jennings @Tuff__CrowdWhy u so quiet now you groupie ass trainer @DrewHanlen where is the group text chain now!!!! U the biggest basketball groupie trainer everTyrese Haliburton's trainer did not take kindly to Jennings' comments and put him down brutally by pointing to his playoff failures. Hanlen also mentioned that he will not be wasting time on Jennings' take since he has two clients to prepare for the finals, Haliburton and the OKC Thunder's Chet Holmgren.Drew Hanlen @DrewHanlenI’m getting two of my clients (Haliburton & Holmgren) ready for the finals so don’t have time to waste on your dumbass takesSide note: Maybe if your trainer would talked shit to you, you wouldn’t have shot 37% from the field & 23% from 3 in the playoffs while never winning shitBrandon Jennings spent nine seasons in the NBA, averaging 14.1 points, 5.7 assists and 3.0 rebounds through 555 games. Unfortunately, his playoff career left a lot to be desired, as he recorded just 8.9 points, 2.6 assists and 2.0 rebounds per game while shooting 37.2% from the field, including 23.8% from 3. In nine years, Jennings made the playoffs four times but never managed to make it past the conference semifinals.The furthest he got was in 2017 when the Boston Celtics eliminated his Washington Wizards in Game 7 of the Eastern Conference semifinals.Drew Hanlen's clients, Tyrese Haliburton and Chet Holmgren, have been solid in the 2025 NBA PlayoffsAlthough Brandon Jennings is criticising Drew Hanlen, the trainer's work is undeniable. Two of his clients, Tyrese Haliburton and Chet Holmgren, have played their heart out in the playoffs this year and are headed to the NBA Finals.Haliburton recorded 21.0 points, 10.5 assists and 6.0 rebounds in the Eastern Conference Finals to lead the Indiana Pacers past the New York Knicks. On the other hand, Holmgren is averaging 16.4 points, 8.6 rebounds and 2.0 blocks through 16 playoff games this year.The Pacers will head to Paycom Center to take on the Thunder in Game 1 of the NBA Finals on Thursday.
