I think exit will agree with me on this one... they won't.
Chad has showed me something this year. Granted, it wasn't against the best of defenses but he's still as smart as ever, and he's finally getting some help from WRs. I see them at a competiive 7-9, maybe 8-8.
Mangini at age 35 already is getting some fat, looks a little bit like Parcells with those man boobs. I can only imagine what he'll look like in 20 years.
