Re: David Vidal
Even if H-Rod can play a decent 3B, his bat will be much less valuable there than if he sticks at 2B. Vidal's bat appears stronger and he mans the position better, so I don't think he'll be a problem. As for Francisco, this season will go a long way towards determining how exactly he fits into our plans. Rolen's contract expires after the year, so he's either going to have to be replaced by Frazier, Francisco, or something external. Those two have been hovering in AAA for a while now, and I'd say this next season is now or never for determining if they're MLB starter material.
But Vidal's way isn't all that clogged... I'd say he has the easiest positional path to the majors of all as of today.
