That's a fair point, although I think it's also worth considering it an illustration of how few PA his MLB downturn was if 1 week essentially erased it. We do have ~900 PA before this year of him having an MLB quality bat(especially in CF), so I don't want us to overstate the risk. That is the risk though, Happ is a bit of a wild card, and he hasn't spent so much time in CF that we can be uber-confident in how to peg him defensively either. Yeah I mean, there's two options/conversations here: 1. You essentially throw out last year, take his MLB PAs from 2017 and 2018, slap it on 600 PAs, and he's a roughly 2-2.5 win player in center field. Not terrible, but it means you're looking at an outfield that's going to really struggle to top like, 10 WAR total if you lock in Schwarber and Heyward next to him. 2. You take last year as, if not close to the norm, a step forward. He's not going to OPS .897, but whatever he worked on eventually had a positive effect, and he can put up roughly a .250/.325/.500 slash line over the full year (admittedly a little optimistic, slugging wise). You basically have Brett Gardner, who put up a .251/.325/.503 slash line with slightly positive defensive value for 3.6 WAR. Awesome. The issue with someone like Happ, even if he ends up with these types of numbers, is that he seems the type to do it in streaks, and he's the kind of player that is the first to be blamed/turned on when things aren't going well. To put myself in David Ross' head, Happ hasn't "earned" the rope to ride out a few weeks for 40% K rates. So even if you're optimistic and think he can put up 3+ WAR in a full seasons worth of PAs, does he even get that chance?
