Don't really think it's Vince, at least not to make that much of a difference. I think it's Stan Van Gundy's offense and him pretty much being okay with the Magic shooting three pointers all the time, at any point in the game, in any situation, in transition, on a delayed transition, in the half-court set, off turnovers, on on-of-bounds plays, off of offensive rebounds. He's pretty much cool with three point shots no matter what the situation is and how they get there. It's SVG's job to make sure Dwight Howard gets more touches, gets more involved in the offense, more than just a few token dump downs.
Vince doesn't help, but you can say that about guys like Pietrus and Matt Barnes too, who both have no conscience when to put up long jumpers or bad shots in general.
