I'll just do W/L and ERA, but let me start by saying anything under 3.5 is an extreme stretch in the ALE.
Schilling - 17-10, 4.25 ERA
Beckett - 18-9, 4.3 ERA
Matsuzaka - 14-7, 4.3 ERA
Wakefield - 12-14, 4.5 ERA
#5 Starter (sans Clemens) - 10-16, 4.7 ERA
That's an approximation of 71-56 out of the starters. We'd need 25 wins out of the 'pen to get to the playoffs, IMO.
If Clemens comes on board it's a whole different ballgame.
