I agree with this with one condition. They need another starter so Aceves can go back to the bullpen. As things are currently, Bard and Aceves are rolls of the dice as starters. The back of our bullpen is Albers, Melancon and Bailey. Last year it was Aceves, Bard and Papelbon. I don't see this year's bullpen as close to comparable with the 2011 pen unless Aceves moves back to the pen.
As to the health issue, when was the last time that Beckett, Buchholz and Lester all stayed healthy throughout the season? Depth important, and SIlva et al are not depth.
