Based on what? These awesome numbers from Coco Crisp?
OPS by month:
April: .612
May: .611
June: .816
July: .896
August: .665
September: .695
Or maybe the fact that Coco is inferior in both Zone Rating and Range Factor with half the assists due to his Damon-like throwing arm? To be fair, Coco is pushing 30 while Melky is pushing 23; that's seven extra years worth of chances to get injured before retiring for Melky.
