Let me guess this is fielding % and errors more than anything. What about range, what about balls picked out of the dirt, the number of throwing errors saved?
If you saw Dougie M everynight scooping Koskie or Guzman's throw out of the dirt, you'd understand why this bothers me. Honestly it's not Olerud, he's good. But Dougie M is so much better in terms of doing more things well with the glove.
