Here is my best guess...
Schilling 15-8 4.00 Will still be good
Beckett 18-10 3.90 Hopefully will have a comeback season
Matsukaza 13-7 3.50 Will baffle hitters
Papelbon 14-8 4.00 Will be very reliable
Wakefield 13-10 4.20 The usual Wake
If these predictions are correct, we will have a very good rotation.
