Schilling turned out to be a nutjob off the field, but on the field he was a hellacious competitor. The bloody sock game seems to have become a joke, but in real time, it was pretty damn amazing. The surgery that was done on him, I'm not sure many other players would have even said yes to it.
And in the 2007 postseason he was obviously not 100% but still came through. Those were the last games he'd ever pitch.
