@BeddieKU23 I would agree his stock hasn't been impacted by his injury yet. Key word there is yet though. If he sits out the rest of the season that won't be the case though and some front offices will have long term durability concerns along with questions on whether he will be overly cautious with injuries when he get to the NBA or if he will be willing to play through minor injuries in the playoffs. Maybe in some years that doesn't matter, but you have AJ with a similar long term upside and Boozer whose floor is probably a plus starter in the NBA. Even then it still depends on the team picking, but sinking money into an injury prone star is an easy way to take yourself out of running for a championship, especially with the new CBA. DP has plenty of reason to show this isn't going to be a lingering issue the rest of his career if he can.
Also add in that these players are aware that their marketability is important. Showing out in conference play and the NCAA tournament is the best way for DP to gain there.
Plenty of reason for him to play, and once his hamstring is fully healed not much downside to playing. Not like he is going to stop training/practicing leading up to the draft and there isn't a significant difference in injury risk between that and games.
