"Punting" Catcher like Flow/Zook over the last two years???
Better framer, better fit than Zook as a LHH, if Mac's 2018 really was because of injury you just upgraded the position for $2 million.
Steamer projections for Mac are 75 games, 11 HR, 1.2 WAR. For what he's getting paid with his framing and replacement of Markakis' veteran presence, I'll take that all day for that price - and it has nothing to do with being an old-timer.
