Between the guys who were busted for PEDs and the guys who belong in the Harold Baines Hall of Very Good for a Long Time, I think my favorite case would be made for Andrus Jones.
I will say they hired from all over the place. Wish Boston would have gone too, but it is a better start than any regime change we have had in a long time.
As has been oft quoted around these parts, the Sox had a positive 1.7 WAR from the catching position last year without any contribution from Yaz. I could see adding one more back of the roster type guy, but not much more than that.
