Yes, but you can't leave aside the fact that he had far, far, far, far more talent to play with. Of course your 2pt % will be higher in that regard. He was a 4th/5th option. He also had better shot selection, because there were far more open shots to be had, given the talent difference and a well run offense.
Vital is a 5th option who has been forced to be 2nd/3rd his entire career. And yes, he has natural poor shot selection on top.
Rashard also had better coaching.
I'm not even trying to bash Rashad. I loved the guy. But he was limited as a player. He had one elite skill: being able to hit big @!#$!@ shots. And on a good team, that's usually more useful than being an all around marginal player.
