Funny--I posted the pros of going after Lewis in the "why so much love for JP" thread and got flamed for it (thanks mogamezdog)
There would be financial benefits of Lewis vs. going after Peppers, who just wants too much. We all know Ray acts like an ass sometimes, but you cannot dispute his will to play hurt, or his fire that he brings to the field every wk. Not to mention his overall talent. I know he's getting older, but you cannot judge every player by the exact same age standards--some can play another couple,few yrs.
Thinking about Ray Lewis and Mayo on the inside, coupled w/ AD and (Woods, Crable, Draft Pick) on the outside sounds pretty good to me. I'm sure he'd pick up the system just as quick, in all actuality, he'd probably wear the green dot and relay the plays too. Just throwing out the positives, we could do ALOT worse than Ray Lewis. I imagine he'd chill a little with the attention, and certainly has the ability to be quite a team player.
