Last season: 7-9, third place.
Coach: Brian Billick (37-27), fifth year with Ravens.
Pressing question: Can the Ravens reach the playoffs with a rookie quarterback in Kyle Boller and a weak receiving corps?
Feeling the heat: After four years of shuffling through retreads, Billick got the quarterback he coveted - Boller - in the draft. Now Billick needs to stop the merry-go-round at the most important position.
Key reinforcements: Corey Fuller brings a lot to the team at cornerback, and Gary Baxter has adjusted to free safety. Frank Sanders and Marcus Robinson should stabilize the receiving corps.
A lot rides on: Establishing a running game. If Jamal Lewis can run effectively, it makes the QB's job easier.
Best-case scenario: If the defense takes the next step and the Ravens get solid QB play, they could return to the playoffs, perhaps even challenge for the division title.
Worst-case scenario: If Boller plays like a typical rookie, he will cost the Ravens at least a few victories. That would be enough to keep them out of the postseason.
Last season: 2-14, fourth place.
Coach: Marvin Lewis (0-0), first year with Bengals.
Pressing question: Will QB Jon Kitna play well enough to keep No. 1 draft pick Carson Palmer on the bench and in a learning mode this season?
Feeling the heat: Returning offensive coordinator Bob Bratkowski. The idea is to buy time for Palmer by playing Kitna or Shane Matthews.
Key reinforcements: After losing LB Takeo Spikes, the Bengals recouped nicely by adding three players - LB Kevin Hardy, DT John Thornton and CB Tory James - to improve the defense.
A lot rides on: Whether Lewis can sweep away the cobwebs of pessimism that infest the franchise.
Best-case scenario: If Lewis can restore defensive clout after a bad year and RB Corey Dillon stays healthy, the Bengals might approach eight wins.
Worst-case scenario: Kitna bombs, Palmer gets thrown to the wolves, the defense doesn't pick up Lewis' new system. Then the Bengals get a top-five pick again.
Last season: 9-7, second place. Lost wild-card game to Pittsburgh, 36-33.
Coach: Butch Davis (16-16), third year with Browns.
Pressing question: Will QB Kelly Holcomb be able to generate enough points in what promises to be a down defensive year?
Feeling the heat: QB Tim Couch. The first pick in the 1999 draft has lost his job to a journeyman and will receive $6.2 million as a backup this year.
Key reinforcements: Center Jeff Faine, the Browns' first-round pick, wasn't a flashy choice, but he may give the offensive line an attitude.
A lot rides on: The defense improving its No. 27 ranking against the run. The Browns cut all three starting linebackers and replaced them with second-year players.
Best-case scenario: Holcomb performs as he did in the playoffs last year and the Browns' defense plays well enough to reach the postseason.
Worst-case scenario: Holcomb plays like a career backup and Couch can't rescue the offense. In that case, the Browns take a serious dive.
Last season: 10-5-1, first place. Lost divisional game in overtime to Tennessee, 34-31.
Coach: Bill Cowher (109-66-1), 12th year with Steelers.
Pressing question: Will QB Tommy Maddox match last season's strong performance and earn a contract extension, or is he a stopgap measure?
Feeling the heat: RB Jerome Bettis, who lost his starting job. There are a lot of miles - and pounds - on The Bus, and injuries finally have taken their toll.
Key reinforcements: First-round pick Troy Polamalu, a hard-hitting safety, gives the Steelers some sizzle in the secondary.
A lot rides on: Whether Marvel Smith can replace left tackle Wayne Gandy, who departed in free agency. Smith played right tackle last year.
Best-case scenario: Maddox completes the team's transition to a passing offense and guns the Steelers deep into the playoffs, if not the Super Bowl.
Worst-case scenario: Maddox doesn't deliver and the offense struggles. That would dictate a January at home.
Last season: 9-7, second place.
Coach: Mike Shanahan (89-59), ninth year with Broncos, 11th in NFL.
Pressing question: Is QB Jake Plummer the solution or just another guy in the Broncos' bid to replace John Elway?
Feeling the heat: Shanahan is just 34-30 since Elway retired, and 0-1 in the postseason.
Key reinforcements: Plummer and DT Daryl Gardener are expected to take the Broncos back to the Super Bowl. The team needs first-round pick George Foster to help shore up a shaky offensive line at OT.
A lot rides on: Plummer's presence in the locker room. The Broncos made a big stink about departed QB Brian Griese's lack of camaraderie.
Best-case scenario: With strong supporting units, Plummer finally reaches his potential and takes the Broncos back to the championship game.
Worst-case scenario: Shanahan can't harness the mistake-prone Plummer and the Broncos are left facing another QB change.
Kansas City Chiefs
Last season: 8-8, fourth place.
