Panda's not a liability in the field. Just because he's fat doesn't mean he's a liability. he's at worst average. Utley and Zobrist still hit enough home runs to be equivalent to what Bryce did this year (that is, the role of the #2 lefty power guy), and I expect Bryce to step up next year as the #1 lefty power guy in the line up to replace ALR's production. Getting Panda would be an upgrade, getting Zobrist or Utley would be a backfill move.
