Again, though the grapevine Mookie and the Sox had a couple of issues. One, he was ambivalent about staying in Boston. Never really felt truly connected with the city etc etc. He wasn't Ortiz. Secondly the Red Sox rightfully had concerns over his body type as he ages and his penchant for his inability to hit good pitching in the playoffs. Thirdly, Mrs. Betts wasn't a fan of Boston, and was/is more of a Miami/SoCal kinda girl.
That had a lot to do with the Red Sox not paying him. IF there is anyone that left the Red Sox that should piss people off it was Lester. I will never forgive them for doing that he should have retired a Red Sox.
Mookie is a red herring. Much like people are slowly realizing the turd that Devers was, more people need to understand the details of the Mookie trade.
