We don't need a 3B that SLGs .500 plus. We'll take his superior defense to make up the difference.
I still don't get the criticism. Lowell can't play defense anymore, he's average on a good day, immobile on a bad day. As for offense, Beltre will pretty much give you the same output you would expect from Lowell, possibly even more considering Lowell's age. Other than Beltre and Lowell, what other options did/do we have? Move Youk to 3rd and get a top tier offensive 1B is pretty much it, but would cost a lot of talent.
