Barnhart will, in all likelihood, regress to his averages going forward... which would make him the best player at the position on the roster, as expected coming into the season.
But tho it's a small sample size, the situation that AJ finds himself in with this three catcher situation makes me wonder how necessary that trade was in the grand scheme of things. I don't really mind what they gave up in the trade (ie. Quintana), but for a guy that was talked up a lot in the offseason and someone for whom extension rumors have swirled, Barnhart has been underwhelming (so far)
As the situation sets right now, the likelihood is that the Tigers will have to hope Garneau can sneak through waivers soon.... in terms of the depth at the position, at least until Dingler is more established and Rogers shows signs of coming back, he would be tough to lose.
