That's so false it hurts.
If you believe in sabermetrics (which the whole game does now) he is literally one of the best players in the game.
That's not hyperbole- 7th best WAR in baseball. The only reason he hasn't been picked up already is because teams that are interested in him at this point are fringe contenders (or worse, like the Mets) and they don't want to give up a top pick to get him.
