I don't think he'll ever be a true PP QB, in the way the aforementioned players are/were; however, I actually do think that Provy could be a semi-successful as a PP QB if he were to make a few adjustments to his game while on the PP. When you have a guy like Giroux and a secondary playmaker like Jake on your PP you don't need to be a primary playmaker. I can see a scenario with the personnel we currently have where he could be successful. He would need be a distributor of the puck, which he can do. It would be nice if he could develop a head fake or shimmy (really anything to buy himself an extra second with the puck) or develop consistent no look passes and really open his game. But just as a role of distributor, I think he could successful. However, he would need to understand that role, and not attempt things he can't do.
And, I think that's his problem - he's been too selfish on the PP. He holds the puck too long, and is prone to taking poor shots on net. Now this is pure speculation, but it wouldn't surprise me if he believes he's better at PP QP than he actually is.
All of this should be moot, however, as to me the problem with him on either PP1 or PP2 is that we have a better in house options and better options in the pipeline.
@Magua mentioned this previously, and I am in agreement. There's no point in trotting him out there when we have better options ready to go now, and potentially better options in a few years. If we didn't have other options, or we were buying time for others, then send him out there. But since we have other options....
