That's a really big buffer. I'm guessing Liberty is willing to go to 120 but would prefer it lower and may force a firesale if attendence doesn't rebound.
But basically it sounds like our Payroll can stay the same as it was last year, Right now we're at 81M with arb players Medlen, Minor, Venters, Walden, Beachy (really can't see us letting Beachy go, no way does he get a raise from his 1.5M and he's worth that) Pena and Carp. Of that group only big cost will be Minor who'll probably jump from about 4M to 6 or 7.Walden will probably go to 3, Pena should stay around 1, and carp is at most 2.
So we have a healthy chunk of flexibility if we only have say 10M in arb, that leaves about 20M to play with. Meaning we can keep Ervin, and get someone else (like my idea of trading Johnson and signing Headley)
