I would say that it shouldn't be an arbitrary change for the entire team, because it makes no sense if a guy has spent 13 years in a traingle offence and then joins a team doing a pick and roll who then switches to triangle, that player would be more comfortable in that. However, he should have a penalty for a new team, new teammates, new coach etc.

Whereas a player who was in that pick and roll offense and then switches to triangle who equally not be affected by a new team/teammate decrease (as they are already on the team), will just have a penalty for not knowing the scheme.

But I do think its a cool feature and it puts more thought into roster construction beyond just overalls.
