Yeah, 28% of the team's wins isn't bad. He could probably have 2-3 more wins if the offense didn't disappear after the all-star break and the bullpen didn't go through that 6 week phase where they couldn't hold a lead if the other team stopped swinging.
I'm watching from a distance at this point, but I lived in New England for years and still thumb through the Boston papers. About the Red Sox, last year was all about the collapse. This year the attention seems to be infighting and finger pointing and the fact they already more or less blew up the team.
