Isn't this a decent comp for Schwarber? http://www.fangraphs.com/statss.aspx?playerid=11003&position=C/DH Evan Gattis was a terrible defensive catcher last year and was worth 2.2 WAR over 108 games. Extrapolate that out to ~125 games and you're looking at 2.5 WAR or so. If Schwarber is better offensively than Gattis was (which is likely due to OBP), it is likely he could be worth 4 WAR even while being a butcher out there. Derek Norris was also terrible on D, actually worse than Gattis, but had a better OBP, but worse SLG, and was worth 2.6 WAR last year. http://www.fangraphs.com/statss.aspx?playerid=6867&position=C So, yeah, Schwarber could end up being extremely valuable as long as he's not completely incompetent behind the plate.
