Come one man, that's still a mountain more of evidence than your theory. We see what we want to see, Sox made three contract offers to Betts, and he gave every indication he wanted to go to FA.
Again, and again, I think this is the case of us fans seeing what we want to see and putting our fingers over our ears and going "la la la la la la la la" Betts was gone, Betts was never going to sign an extension here, maybe the Sox could have signed him in FA but they would have had to top 12/365 at the very least because we know LA would have offered that.
