Just as intriguing as the NFL playoff matchups is the league's coaching carousel.
While much of the football world is focused on Green Bay, New England, Indianapolis and Dallas, another part is tracking the doings in cities with coaching questions.
Here's a look at the coaching carousel:
After Monday, Washington's coaching situation becomes the most pressing, and intriguing, in the league.
Gibbs has one year remaining on his contract. The feeling within the organization throughout the season was that he would return. But Gibbs did not sound convincing Monday.
He made it sound as if he and Snyder have plenty to discuss. Gibbs never has wanted to leave Snyder, who has treated him royally, in an unfair position. But Gibbs said he believes these Redskins are on the right path, with the right quarterback and the right personnel. If ever there were a time to walk away, this might be it.
Gibbs said he would push to get resolution as soon as possible. But it's also entirely possible that Gibbs has his mind made up and Snyder won't be able to talk him out of it. Plenty more to come here.
Time is not a constraint for the Ravens. They will take as much of it as they need. They plan to interview eight to 10 candidates before deciding whether they want to speak to any again. But the process is in full swing.
If Harbaugh were to land the job, he would be expected to bring Eagles quarterbacks coach Pat Shurmur along as his offensive coordinator.
There is another candidate that cannot be overlooked. The Ravens also are expected to interview Titans defensive coordinator Jim Schwartz, whose team was eliminated from the playoffs Sunday in San Diego. Baltimore is familiar with Schwartz and his style; the Ravens and Titans have squared off against each other in the playoffs.
Schwartz is regarded as one of the game's bright young defensive minds, and Baltimore wants to spend time with him as well.
But if the choice is anybody other than Sparano, it would be the equivalent of an upset of the New England Patriots.
Atlanta is expected to interview one more general manager candidate in the next 24-48 hours, after it wraps up its interview with former Ravens defensive coordinator Rex Ryan for its vacant head coach job. Ryan also interviewing for the head coaching job in Baltimore, but is not considered a favorite there.
The Falcons have been tight-lipped about their entire process, having been turned down by Bill Cowher and Bill Parcells. But they are moving closer to a resolution on a general manager, which would precede their head coaching hire.
How Oakland's coaching staff will look next season is uncertain. What is certain is that there are significant questions surrounding the Raiders. As usual, they start with their head coach.
When Lane Kiffin took over one year ago, he did so with assurances that he could pick and choose his assistant coaches. If Kiffin had his choice, defensive coordinator Rob Ryan would not return to Oakland next season. But the Raiders already have announced that Ryan, respected in league circles and with one year remaining on his contract, will come back.
It has intensified the staredown and standoff between Kiffin and Raiders owner Al Davis. As the season went on, Kiffin felt more and more emboldended to stand up to Davis and request things be done the way he felt they should. How these two will hash out their differences is one of the biggest coaching questions of this off-season.
For now, the belief is that Kiffin will return. But with unpredictable Oakland, which often has waited to make coaching moves, anything is possible.
Tampa Bay Buccaneers
Those close to the situation expect Gruden to receive an extension this off-season. Not only is Gruden expected to return, but the feeling is his defensive coordinator, Monte Kiffin, will as well. The senior Kiffin's contract expired after Sunday's wild-card loss to the Giants.
Despite the conjecture, the senior Kiffin will not be united with his son in Oakland. The Buccaneers will likely do everything possible to retain one of the finest defensive coordinators in the history of football and maybe the most important assistant coach the franchise has ever had.
