That's a good list of guys we dealt, and it's interesting that the 10 pitchers combined to win a combined 499 MLB games (...so far; Montas and Kopech are still active in the bigs, while Espinoza has yet to make it). That's an average of 50 wins per arm, but that figure is more like a median, since Sanchez, Pavano and de la Rosa won just over 100 each.
Now compare the list to the four aces the Sox acquired for most of them: 685 career victories from Martinez, Schilling, Beckett and Sale (the latter, of course, is back atop the rotation, with already as many Ws as any of the 10). That's an average of 171 wins per stud... each traded to Boston for lesser prospects... when the time was right.
