The thing with the PP iso, to me, is that there isn't much of a chance he makes it to the paint. At all. The step-back jumper is pretty much what he's got left in those situations, and like I wrote, it would probably be from distance, aka the lowest % shot on the floor.
The lack of quickness among our regulars (ex. Rondo) is part of what make VW, who is barely in the league at all, look at times like he's the most dynamic slash/scorer since MJ himself.
So at the backup SF, I don't think we just need a defender, but a bench scorer that makes opposing teams have to plan a bit; someone who can do for us what Jason Terry does for the Mavs, or that guy in Atlanta (brain cramp at the moment).
Yeah, I think we need that.
