Because coming off the bench if WAY more different than what you think and what the stats show (PT)
You don't have time to "feel" the flow of the game, to choose whether you attack straight or distibute...
For example, you remember Tony often being VERY agressive in the opening quarter, taking advantage of the fact that the opposite team doesn't want to get in foul trouble too early...
NOW, whem he comes, he has to be a difference maker STRAIGHT!
+ He doesn't play with the same guys as often, playing in a unit with Bonner, Blair or any bench player is not the same that with Timmy...
Less assists, more attention...
Anyway, I see some advantages and disadvantages, but it's really NOT the same deal for him...
Remember Manu's first quotes years ago when he first came off the bench!
He explained that there was big differences and that he had to adapt his game/production...
