Juiciest story line: It has been awhile since Shawne Merriman put anyone's "lights out." Injuries have plagued him, but the Bills are pinning their hopes for a pass rush on Merriman. If he is able to make an impact off the edge, as he did in the preseason opener (two sacks), it will add a dynamic to the defense that could help change the Bills' fortunes.
Player to watch: C.J. Spiller fell well short of expectations in his rookie season. He showed flashes, but the Bills expect him to be a larger part of the offense in 2011. Buffalo is not short on weapons on that side of the ball, but if Spiller can be a threat, it will take some of the load off Fred Jackson and Ryan Fitzpatrick.
Strongest position: The defensive backs are still the team's strongest unit, even with the loss of Donte Whitner. Re-signing CB Drayton Florence was key, and George Wilson should be a fine replacement for Whitner in a secondary that helped the Bills allow the third-fewest passing yards a game last season.
Weakest position: The Bills did not address the offensive line in free agency, and their fourth-round pick, Chris Hairston, is in no position to play right away. The tackle positions still need an upgrade. Demetrius Bell is not suited to be a starting left tackle, and it's not much better on the right side with Erik Pears.
Juiciest story line: All eyes will be on No. 7 — and he knows it, too. Chad Henne has a lot riding on his right arm. His job, and possibly that of his head coach and general manager, could go down with the ship if he has another inconsistent season. The personnel is there to help Henne succeed, but the pressure couldn't be greater.
Player to watch: Reggie Bush will be worth watching during the preseason, as he is expected to provide the spark the Dolphins' offense could use. Expect them to use him often and creatively. Bush has never played like a No. 2 overall pick, but there's no denying he has the skills. Maybe a new location is what he needed.
Strongest position: The D-line is stacked. It was good last year with Kendall Langford, Randy Starks and franchise NT Paul Soliai. The Dolphins re-signed Tony McDaniel, the unit's top reserve, and they will get Jared Odrick back. Odrick started the 2010 season opener as a rookie before suffering a season-ending injury.
Weakest position: It has to be the QB spot. The team failed in its attempt to trade for Kyle Orton, and the choice to back up Henne — Matt Moore — is not good enough to compete to start. Behind them is journeyman Kevin O'Connell and undrafted rookie Pat Devlin. Henne can change all that with a breakout season, but as of now, it is a weak unit.
NEW ENGLAND PATRIOTS
Juiciest story line: Albert Haynesworth was a dominant force with the Titans, one of the best in the league, but a distraction off the field who made little impact on the field in Washington. If Bill Belichick can get Haynesworth to return to form, the Pats will have a scary-good D-line with Haynesworth and Vince Wilfork a formidable duo.
Player to watch: Despite several veteran additions at defensive end, there is pressure on Jermaine Cunningham to make the leap in Year Two. He will be spending more time at his college position and will be counted on to use his quick burst to wreak havoc in the backfield.
Strongest position: Each unit on the offense is worthy, but quarterback gets the nod. The Patriots have the reigning league MVP in Tom Brady, a backup in Brian Hoyer who played well when he had an opportunity last season and rookie Ryan Mallett, who has a first-round-caliber arm, as the team's No. 3 QB.
Weakest position: It's difficult to find weaknesses with this squad, but the lack of safety depth could be a concern. Patrick Chung is primed for a big season, but many around the league consider Brandon Meriweather to be overrated. Brandon McGowan and Jarrad Page are gone, leaving James Sanders as the No. 3 safety without a whole lot of experience behind him.
NEW YORK JETS
Juiciest story line: Plaxico Burress hasn't played an NFL game in almost three years, with 22 months spent in prison. Rex Ryan and the Jets took a chance on him, and he will be counted on to be Mark Sanchez's tall red-zone target. Everyone wants to know how Plax will look when he steps on the field.
Player to watch: Rex Ryan has been raving about Jeremy Kerley, and considering the exits of Jerricho Cotchery and Brad Smith in free agency and the lack of depth at wideout, the speedy rookie could see some playing time. He should factor in punt returns, as well as out of the slot.
Strongest position: This was a toss-up between the secondary and offensive line, but with questions about the right side of the O-line, we'll give it to the DBs. By re-signing Antonio Cromartie, the Jets boast one of the better CB tandems in the league. Jim Leonhard will be back soon along with Eric Smith as the safeties.
Weakest position: Wide receiver is a boom-or-bust position for the Jets. If Plax and Derrick Mason are productive as Santonio Holmes' complements, then there is no problem. But there is very little in terms of skill and experience behind them, and both veterans are question marks.
