Jalen Duren is only 21 years old and is already an established double-double machine, so he seems the most likely of the two extension eligible Pistons (the other being Jaden Ivey) to get a new contract before October. If the Pistons work it right, it can be hugely beneficial to their cap sheet.
Duren still has question marks as both a defender and offensive player, but he’s shown enough in his early career to predict that we haven’t seen the best of him yet, which makes him a fairly safe investment for Detroit if they want to extend him before the season starts.
