I would not be surprised if there are a lot of games missed this season by various players. While it is not load management in the classic sense of giving a star/vet some rest, but just a way of keeping the development going for players who would not typically be getting game experience. The injury to Vassell has been vague, basically a sore knee. It sounds like the type of injury a player would play through normally. Or glute spasms for Primo?
Later in the season Sochan and other recent draftees should be hitting the rookie wall. Sitting a player for the mildest thing allows for real NBA game time for others on the roster to develop (or not) and hopefully minimizes the impact of the grind of the regular season. Since the goal to focus on improving and if oh, by the way, the team has a bad enough record to score a top three pick, that's gravy.
All I am saying is I am skeptical Vassell cannot play.
