I like Jamal Lewis alot this year. Last season was a miserable failure for him, and with a decent QB at the helm he should find more running room. If he's healthy, I could easily see 12-1300 yds and 8 TDs for him.
I don't think McNair is going to revive that offense. And if he does, all it will do is expose Jamal Lewis. I don't think he's that good anymore.
We'll find out soon enough. Even though he's not as dominant as he used to be, McNair's a step up from any QB Lewis has had in the last five years, and it's not like Lewis is 30 years old. Perhaps he has lost it, but I think he's going to surprise people this year - the guy was running on one foot all last season, and his career average is 4.4, which is pretty gaudy considering last year's sub 4ypc disaster is factored in. I've been wrong before, but I like him to have a pretty nice rebound year.
