Here's my thinking on arb for those guys:
Bailey = 4 million
Heisey = 1 million
Stubbs = 2 million
Leake = 2 million
Those are just guesses, but sort of guaged off the fact that Bailey, whose career bWAR was 0 before this season, got 2.4 million in his first arb year.
I think now is the time to shed some of these valuable cost controlled players before they become too expensive. Unless the payroll is going up in the mid to high 90's.
