Yeah Zobrist is a pretty unfair comparison for anyone.
Morel has a 125 wRC. Zobrist bested that three times, in a four year stretch where he put up a 152, 100, 130, and a 137 (2009-2012). In those 4 years he was the second best offensive player in baseball, which was also aided by pretty fantastic defensive numbers. The Zobrist we got familiar with (124, 83, 123, 83 again in his last (lost) year, although obviously much more OBP heavy vs Morels SLG) is probably closer to what you would hope for from Morel.
I don't think there's enough out there to close the book on him defensively....he seems like a great athlete who has made a significant leap offensively in the last couple years, it's hard for me to imagine he's totally unplayable out there on a permanent basis. Speed is 79th percentile, arm strength is 99th.
Certainly a flawed player, but I don't think you write him off as positionless at this point. 5 more years of control and his ability to hit the ball incredibly hard frequently is too valuable.
