without the howitzer Jose goes from a average (arm compensating for his lack of range) to a below average defender. he's probably bottom 5 in among MLB rightfielders with the shredded arm.
and runners are taking advantage, seeing it again and again
Jose is quite weak at tracking balls over his head (he's fine with balls hit in front of him) and he has a fear of the wall, you rarely see him go up against it and a fair number of long balls that another outfielder will run down fall for doubles or triples
Pompey in RF and Jose at 1B with EE as DH is the best team alignment at the moment IMO
