If anybody truly believes Schaub has Pro Bowl potential, they are really missing the boat on that one. Schaub could become what many call an "efficient starter" and be considered a lesser version of Tom Brady (a la Marc Bulger), but he doesn't have Brady's arm, poise, accuracy, and leadership.
Are these the same people that thought A.J. Feeley was going to be a great QB? I'm not doubting the validity of PFT's sources, because the 1 or 2 that they may have talked to may have said that, but if teams really thought Schaub had that type of potential, more than 2 teams (Atlanta and St. Louis) would have been looking at him as a 3rd round pick.
We'll see though...
But it's also a little early in his career to decide if he doesn't have the poise, accuracy, or leadership(He sure showed a fine role of a Leader in his comeback against the Pats)
