Beckett is the nbr one bad actor in this drama. He most go! At least they will get something in return. As a ten/5 guy he could veto any trade, but given that playing here will become very unpleasant for the smug SOB, I think he'll get the message and want to rehabilitate himself elsewhere.
Lackey is untradeable! If they could work out a deal to send him packing to some baseball Siberia, all the good. If not, I'd tell him that he'll be working out of the bullpen as long relief or a possible spot starter until he has sufficiently readjusted his attitude. I don't think KFC will deliver out there.
Lester gets another break! I get the sense he is a good kid but followed the "role model" of his elder peers. Buccholtz gets a pass because he was injured. But someone needs to have a real heart to heart to keep this kid on the right track.
