If Vick has PG potential, yes. I like long point guards. But I have had the impression that he is not a great ball handler and distributor.
I think the plan was Svi at 3 backing up Wayne, and Brannen at 2 backing up which ever one of Frank/Devonte needed a blow.
Probably Self viewed the time that Brannen and Svi came in as times for them to be on the wings with a single point guard out front running the high low passing offense.
But Self suspended Brannen and Svi has been volatile shooting--way hot, or way cold, so Self has had to ride it out with Frank and Devonte playing extra minutes.
My guess is things will settle down with Brannen back. Probably what happened was that when Self suspended Brannen, Svi began to have to learn two positions and got a little overloaded. It doesn't seem like much, because it is just one wing, or the other on offense. But on defense, it IS a big deal having to prepare for two positions. It meant Svi had to prepare to guard four guys, instead of two, which would be normal. Normally you prepare for the starter and his backup. Svi had to start preparing for two starters and two back ups. Its a lot more game video to watch and a lot more to remember.
Also, preparing for two wing positions in Self defense means learning two different menus of help rules. One wing tends to help with with one post man and the other wing tends to help with the other post man.
Further, it means remembering to funnel to the center in opposite directions on defense.
It may not seem like much to an experienced player, but to a guy still finding his way, like Svi, it could be a jump. And when you start having to think a lot out on the floor, all the things you do best without thinking, like shooting, and reacting on rebounds, and getting the jump on funneling someone, well, those things can suffer.
The point of this digression is also that not only might things settle down for Brannen and Svi, but because everyone will be back to learning one position for each game, it may mean that Vick only has to be asked to learn one position, and so Self can more confidently slip him into some minutes without Vick thinking too much.
