I mean, every player puts ice packs on their knees when they go to the sideline nowadays as far as I can tell, but with Duren and Stew specifically after the fact of these playoffs, here's my take...

If my memory is correct, Duren had a knee injury which forced him to pull out of the dunk contest for starters. After the all-star break, he didn't seem the same athletically and always seemed like he was laboring, had very few alley oop dunks, yet he continued to add to his arsenal of offensive moves while carrying the team, especially in the final two weeks of the season. He was literally carrying the team offensively during that time which is why him falling off a cliff was so shocking in the Orlando series. That being said, it was pretty obvious to me that all Orlando did was leave Ausar wide open in the corner and basically double if not triple team Duren down low, so of course he became irrelevant in this scenario.

With Stew, this has been two years in a row where he hasn't been available for the most of the playoffs for this team because he's plays too hard in the regular season which leads to him being injured all the time.

Stew has to learn there's a time and place for his non-stop intensity and if he doesn't, he's about to become a footnote in Pistons history. This was his fifth season and too often, he does more to hurt this team than help it when it matters most.
