I don't entirely believe that was the actual deal presented. Also, that trade doesn't bring them under the lux tax, correct?
The Sox' main objective was to get under the lux tax, no matter what Henry said otherwise. Any trade that would prevent them from doing so wasn't going to happen.
I think the Sox used the Padres as a spark to force momentum on a trade with LA. I think Bloom all along knew he wanted Price and Betts to go to LA.
