I'm more bullish on the talent of the Jays than most, I guess. There's a lot of talent. Pearson + Ryu should be an excellent 1-2 punch, I think big Murph or Murray could surprise, rotation isn't super rock solid but Shoemaker, Roark, Yamaguchi, Anderson, Thornton, Borucki is pretty decent rotation depth.
The OF is the most glaring weakness, outside of probably Gurriel. Why they haven't signed Puig already is baffling to me.
