Nope. I think he has the potential to be a #2 though, but the problem is that the financial cost involved in him getting there probably is prohibitive.
Though, consider Lester. He became a front-end starter at age 24. Porcello might be able to be that this year, yes, I think that's possible. But that's an expensive risk because if he doesn't get there, he's going to cost a lot.
But I think the Sox should do some homework on him.
