Culpepper -
He Stays. They invested a 2nd rounder, and they'll probably want to give him another chance (most teams place a high value on a 2nd rounder

).
Leftwich -
Definitely gone. Oakland has the biggest need, but I wouldn't be surprised if he went to Cleveland, Tampa, or Minnesota.
Griese -
He Stays. Grossman is too unpredictable, and Lovie is too smart to underestimate the value of Griese.
Simms -
If he was offered a contract by Tampa, then he needs to take it before they change their minds. I doubt he'd get much in FA after sitting out a year.
Brunell -
If we go on a wild FA spree again, and we need the cap space, then he's gone (unless he restructures). I think we'll be quiet in FA, and he'll stay. However, I'm not convinced that MB is happy being a backup -- after all, that's basically why he left Jax.
Holmes -
I'm a little skeptical about him. When I heard about his spinal injury, I thought it was one of those things where the docs would say, "You can play, but if you take the wrong hit, you may become paralyzed or die." If he does come back, he'll probably stay in KC.
Faulk - Hahahahahaha. He'd be a fool to quit his cushy job in show biz.
