Assuming he can start everyday now. Can't DH in the NL. Fact is he's been a meh hitter since joining the Yankees. Good for a catcher but not good overall. Would need massive salary to make it worth on for a performance sense. PR sense it would put some butts in seats regardless.
Unfortunately, those are the types of upgrades we should be expecting. Instead of Ces, Desmond and Lucroy, we will get Kemp, Mac and some disappointing platoon at 3B. Even if it doesn't result in a good team, at least they will be more fun to watch and root for.
