The problem with Campana is his slugging %.
Over the course of his career, DeJesus has put up a 775 OPS. He is off to a slow start but his OBP is in line with his career average (357 v. 356). The problem has been his slugging % which is off this season.
Campana may be good at getting on base, but its the same issue with DBarn- his OPS will never be significantly be higher than 700 and with Campana its because of his slugging % also.
The difference here may be Campana is faster, but over the long haul DeJesus OPS will always be better than Campana's. DeJesus has shown in the past that he will exceed the average OPS standard for OFs. Campana is the 2nd coming of Juan Pierre.
