The whole season was "early in the season".
Still it's more a point about what percentage of the Sox IP this year were handled by AAAA-type pitching. If you count Godley and Brewer as AAAA pitchers, which they should be, over 45% of the IP for the Sox this year were handled by pitchers who were, at best, borderline MLB talent. (And that is not counting the 43 IP from Ryan Weber.)
Godley certainly has had a couple good seasons. But those are in the rear view mirror and he was cut by Detroit prior to signing with Boston...
