I think once fans get it in their heads that a certain player is a slacker, malingerer, troublemaker, or whatever the case may be, that perception is incredibly hard to shake. I never saw any of that in Hanley during his time with the Red Sox. Say what you will about his performance, but he always seemed to have a smile on his face and to be genuinely happy to be here.
I, too, wish him all the best going forward. It wouldn't particularly surprise me at all if he latched on as a 1B/DH somewhere and hit something like 15 homers with an .820 OPS the rest of the season.
