You haven't been paying attention to the Sox roster over the past two years. Nava would be brought up to play left or right, as he did last year. Sizemore would play n center that's why the Sox signed him as insurance. Major league clubs usually feel one can tell how a team will perform after fifty games. It is becoming obvious that Bradley hasn't shown that he can adjust to Major League pitching. The Sox will do the same thing to him that they did to WMB last year if he continues to fail at the plate the way he has to date, they will send him down and call up Nava, assuming he continues to hit in triple A. The sox need another bat if they wish to contend this year. They are probably looking now.
