Why are you using IKF's career numbers? Should we use Scherzer's career numbers when assessing his ability going forward? Human's aren't robots who are the same from year to year, month to month, etc.
Barger hasn't played well recently but give me his upside over IKF's upside in a must win game. I'd prefer to reward the player who was a big reason why we're currently where we are over a dude who got DFA'd by MLB's trash franchise.
