Mussina = Schilling
Wang > Beckett
Johnson
Pettite = Papelbon
Igawa/Pavano
I think Schilling and Mussina are both very able aces and I can picture them both aheing 16+ wins with solid ERAs, could goeitehr way.
Battle of maturity here as Beckett needs to show he's learned from his mistakes and be what he's supposed to be. If he can't, this battle goes to Wang.
40 year old with injury problems and somehwat abd mechanics last year to the fearless 26 year old with command of 4 + pitchers, however this could eaisly swing in teh yankees decision.
Pettite, if he stays healthy can beat out Papelbon but I ahev a lot of optimism in Jon and think he can rack up 13+ wins with a decent ERA.
Wakefield is always reliable to give you a shot in a game, pending your fofense is working. I look for now more than a .500 record and a 4 ERA. Igawa/Pavano are big ?s.
As you see, this could swing either way, both rotations have their own questionables, and it could be very Red Sox or very yankees, or even somewhat of a draw.
