I'm going to dispute your list.
Pats= good- Good system QB. Lots of help around him.
Bills= new guy- Young guy learning the system.
Jets= new guy- Rookie
Fins=replaceable- Questionable track record. Injury prone. Replaceable.
Steelers= good- Solid starter with good track record of protecting the ball.
Ravens= new guy- Limited track record.
Bengals= replaceable- Injury prone, questionable track record; has only had 1 good season.
Browns= bad-Two guys that could both be Pro-Bowl players or busts
Titans= replaceable- A twitchy young guy and an inconsistent old guy.
Colts= good- Probably the best system QB in the league, but the team and coaching around him just fell apart.
Jags= replaceable- Questionable track record, like Cincy their guy has only had one good season.
Texans= replaceable- Injury prone and has not shown he can be consistently healthy and good. Has not done anything of note yet.
Chiefs= new guy- Limited track record. System guy with limited help around him. Unless Bowe becomes Superman overnight, he will struggle.
Broncos= bad- Idiotic coaching staff. Limited ability/inconsistent play for previous team.
Raiders= bad- Young guy who must learn to work withing the gameplan. Freelances too much and not accurate.
Chargers= second tier- Solid franchise starter with strong supporting cast and great running game.
Cowboys= replaceable- Fumble prone, lacks situational awareness, cannot handle big-game pressure. Will always crack.
Giants= second tier- System guy like his brother, but plays in a less aggressive scheme. Tremendous supporting cast.
Eagles= good- Freelancer with injury issues. Finally has help, but from young guys who are mistake prone.
Redskins= replaceable- Idiotic head coach who is married to his system. Nice arm and size, son of a coach. Not very accurate, possibly has too much windup in his delivery to be an effective West Coast QB. Does not make big mistakes, though. Is the exact opposite of Romo in that regard. Plays too careful, needs to take more risks.
Lions= bad- Rookie. Alternative has talent and a track record, but the coaching staff has already deemed him a stopgap.
Packers= new guy- Solid starter, limited track record. Could be Marino, could be Anderson. We just don't know yet.
Vikings= bad- A mess.
Bears= replaceable- Limited track record, questionable attitude. Feast or famine playing style will not go over well with his high profile defense.
Falcons= new guy- Limited track record. Time will tell.
Panthers= replaceable- Inconsistent and injury prone.
Bucs= bad- Rookie and several journeymen. Position is in transition.
Saints= good- Very good system QB. In spite of his lack of size, talent, or arm he is very productive. Coaching staff believes in him and lets him throw the ball alot.
Seahawks= second tier- Inconsistent track record, injuries. Only had one good year, but lost the SB. Solid starter.
Cards= good- One of the best system QBs in recent history when he has a good supporting cast. Very accurate, great release.
Niners= bad- A mess. Team will likely revamp this position next offseason to get the new coach the player he actually wants at this position.
Rams= bad- Rumor has it they are interested in Vick. Never a good sign.
By my count:
6 good ones.
3 second tier (I downgraded Cincy)
9 replaceables
6 new guys (1 year of solid production or less)
8 guys that outright suck.
Basically that comes down to 9 good players, 15 guys that are mediocre, and 8 bums. Not very impressive.
