This is a preliminary list based on those not signed at the moment. Nothing here is official at the moment
MRs are no longer eligible, except for rare case by case FAs (like if Hoffman were a FA).
There's a new twist to this regarding older FAs. If your otherwise-eligible FA to be is about to turn 35 you must first show you're willing to extend him for at least 2 years beyond his 35th birthday (so til 37 at least) for a very reasonable amount to gain free agency compensation. This puts the decision on the GM whether or not the risk is worth it and whether or not he gets compensated.
The specifics on this twist may be tweaked for next offseason as I think about it some more, but for the time being if I see an honest effort made to sign the guy long term to a risky deal I'll allow it. (Gehrig and Oh are the only two in question here, though, I believe)
