I can go with best Sox CF I've ever seen. Unless someone is more aware of whom I have seen as a CF, it is hard to say that makes him overrated.
Granted, my recollections of Lynn are from before I knew or cared about defense. So who are my other candidates? Armas? Damon? Burks? Crisp? Ellsbury? Steve "Psycho" Lyons?
Darren Lewis came here with a rep as an outstanding defender, and even had some hardware, but I just don't recall anything special about him (which means nothing). Ditto Damon Buford...
