He couldn't crack the starting lineup in KC and his fielding is atrocious. He has botched several plays for the Sox already at 2B, SS, 3B and RF. Did you see how he executed that run down the other night while playing SS. He looked like a little leaguer.
Pedroia wasn't brought up from the minors after 2/3 of the season and thrown into a pennant chase and a post season. When he came up in 2006, the team was out of it. And he was terrible in 2006.
