Robbie had 0.8 WAR two years ago, and 0.5 last year. He definitely did not look like a replacement player prior to this year. I acknowledge that players get hurt--that's why the FO signed LaMarre to go along with Granite--with the DL now at 10 days, if one of those guys get hurt, you bring them up for defense. The greater point is that it is hard to find good players. There are 90 starting outfielders in MLB--last year only 48 outfielders had a positive WAR. By that definition, Grossman was better than the SECOND best outfielder for 12 teams. There are more positive WAR outfielders this year, but it's still only 63, which means essentially every team is trotting out a sub-replacement level outfielder every day. Also, I'm not sure what about Kepler's .969 OPS against lefties suggests he hasn't figured something out.
