95 RBI with Ellsbury, Pedroia, Crawford, and Youkilis in front of him? Naw...you're underrating the whole team. Assuming no injuries, Gonzalez'll have 20 more than that. I'm not a blind fan. 115 RBI is reasonable, all things considered. And I'll agree with you on around 35 homers.
For his career, you're right, Wells hits lefties pretty well. In 2010, however, Wells only hit .198 against lefties.
I think the Red Sox as a team are overrated, but AGon should have over 100 RBI easily. He's never had this kind of help in a lineup before.
What the Red Sox are really going to miss is the production they got from Beltre last season. Looking at the stats, he was easily one of the top 5 players in the American League last year. Everyone seems to be ignoring what a big loss that was, and AGon will have to have a very good season to offset it.
