Questioning the AFC

If you're a Mets fan this is the day you've been waiting for since the All-Star Break: Today the NFL kicks-off its season in Pittsburgh.

The classic between the Steelers and Cardinals feels like ages ago while it also feels like it happened last week. Strange how that works.

The offseason has been a long one. Between the Draft, the trades, head coaches being fired and hired and some big players (Albert Haynesworth) moving through free-agency the NFL really doesn't have much quiet time.

Yet, after all these months, there are still questions abound.

Training camp has come and gone, meaningless football -- that fans put way too much stock into -- is over till next August, but every team in the league has at least one unsettling situation. Many have two or more.

Here are the biggest questions facing AFC teams. The NFC will take its turn before it gets its season underway Sunday.

Teams appear in order of predicted finish.

AFC EAST:

Patriots:
How's the knee?
With Tom Brady back the Pats are once again Super Bowl favorites. But, something very small can derail everything, about the size of a knee, more specifically Brady's knee. Bill Belichick is still reluctant to say which one. The other issue is: Who will run the ball? For all the talent this team stock piles, there is not a decent running back on the squad.

Dolphins:
Will Penn. need relief?
Chad Pennington is coming off his second come-back player of the year award. While that shows tremendous persistence on Chad's part, it also means he has issues staying on the field. Should the need arise, is Chad Henne ready to step in? Or will the 'Phins be forced to move to all-Wildcat offense?

Jets:
Which Matt will Mark Sanchez resemble?
Matt Ryan who carried the Falcons to the playoffs or fellow USC product Matt Leinart. To be fair, it may be difficult to judge, because the Jets also have a few questions to be answered at the receiver spot.

Bills:
When/Will T.O. .......?
When Terrell Owens is on your roster every query must involve the reality-show star. Will T.O. get along with his quarterback? How long before T.O. gets frustrated? Will T.O. cry at a press conference?

AFC NORTH:

Steelers:
Can a team repeat in this NFL?
Repeating is one of the most difficult things to accomplish in sports. Every game is the opposing team's prove-it-game. The defending champs have some clear-cut games on the schedule -- no matter what the Lions or Raiders are trying to prove they don't have a shot against the Steel Curtain. However, there is still some uncertainty on the offensive line, and don't discount a tumultuous offseason for Ben Roethlisberger.

Ravens:
Flacco? Rex? Ray?
Is Joe Flacco a fluke? Will losing Rex Ryan to the Jets hurt the defense? Is this the year Ray Lewis begins to show his age? This team will take a significant step back if any of these questions are answered to the affirmative.

Bengals:
What happened?
The franchise was a joke for a decade, then turned it around and were on the verge of big things. Now, they're back where they started. Will Carson Palmer stay on the field this year?

Browns:
Mangenius or Mangidiot?
It wasn't very long after the Jets fired Eric Mangini that the Browns hired him. Early in his head coaching career he was a genius, as time went on he became a pain in the rear. Need proof, Mangini still has not announced who his starting QB will be.

AFC SOUTH:

Colts:
Is this the year?
Losing your head coach (Tony Dungy) and one of the best receivers in history (Marvin Harrison) is going to cause some problems, there is no way around it. How big a step back the team takes -- if any -- will rest on the broad shoulders of Peyton Manning, as the franchise already does anyway.

Texans:
Is this the year?
This team has been on the verge of big things for some time now. Andre Johnson is among the top receivers in the game. The running game is dangerous. The front-seven is deep. The one piece missing is QB Matt Schaub taking the next step to being a premiere NFL passer. Come to think of it, with a top wideout, strong running game, solid pass-rushers and a QB on the verge, the club is reminiscent of a Giants squad that not too long ago beat a certain Patriots team 17-14.

Titans:
Can Kerry stay healthy?
Kerry Collins is coming off a very serviceable season. The wide receiving corps is much improved with the additions of Nate Washington and Kenny Brit but Collins' age (36) has to be taken into account. Can Vince Young step in and hold the team together if Kerry goes down. A few bad games could end their season in a very deep division.

Jaguars:
Can they rebound?
The Jags went from 11-5 to 5-11 in one season. They were one of the darling picks going into the season, but it all came apart. Coach Jack Del Rio got rid of some guys he thought were a negative to the team. It will be tough to get more than eight wins in this division but that kind of improvement will be necessary to keep the heat off Del Rio.

AFC WEST:

Chargers:
Will it -- finally -- all come together?
San Diego has long had the most talented offense it the league, now it's time for them to step-up and play like it. In a cheese cake of a division -- which should be locked up by Thanksgiving -- the Chargers should roll into the playoffs. What LaDainian Tomlinson (there is only one LT, and he played linebacker for the Giants) has left remains to be seen. And whether Shawne Merriman is pushing himself right out of football, a la Plaxico Burress, also warrants (no pun intended) keeping an eye on.

Chiefs:
Is Cassel the real deal?
Matt Cassel stepped in for Tom Brady and did a fine job. Was he a product of the system or is he legitimate NFL QB? New coach Todd Haley has brought some tough love to K.C. but long-term success for this franchise will depend on Cassel.

Broncos:
What should we expect?
Josh McDaniels replaces Mike Shanahan as coach and almost immediately the two best players on the squad are unhappy. Jay Cutler is now in Chicago and Brandon Marshal is in a contract dispute. Outside of Knowshon Moreno is there any reason to watch this team?

Raiders:
Is there a foundation in place?
Let's not forget that the Raiders went to the Super Bowl in this decade, they're not quite the Lions. It's been a disaster since then but there may be a decent base that will not fully take shape for a couple of years. Does JaMarcus Russell have anything? Is Darren McFadden a premier number-one back? Was it head coach Tom Cable who threw the punch that broke assistant coach Randy Hanson's jaw? Whenever this team does come around, it has the most unknown great player in football, Nnamdi Asomugha, at cornerback.
