We are now a Herm Edwards firing away from the most tumultuous year of head-coaching changes in NFL history. To date, 10 teams have changed head coaches this season, tied for most in NFL history for a single offseason.

Cleveland will not waste any time trying to fill its general manager vacancy. Ravens director of pro scouting George Kokinis is expected to interview with the Browns as early as Monday.

When the St. Louis Rams hired Steve Spagnuolo as their head coach Saturday, it had ripple effects with the New York Giants and Philadelphia Eagles.

The New York Giants have been planning for the day that defensive coordinator Steve Spagnuolo would leave since last season, at least.

The St. Louis Rams’ hiring of Steve Spagnuolo impacted two New York franchises. It means the Giants lose their respected defensive coordinator. Just as significant, it positions the Jets to hire Baltimore Ravens defensive coordinator Rex Ryan as their head coach.

If Jason Garrett had landed the St. Louis Rams’ head-coaching job, he was poised to bring former Panthers and Texans head coach Dom Capers with him as his defensive coordinator.

Groundhog Day usually overlaps with the Raiders’ nearly annual head-coaching search. Oakland always takes more time than any other team, and this year has been no different.

After some time away, former Broncos coach Mike Shanahan is more inclined than ever to take next season off.

There is at least one thread that ties together the teams involved in this offseason’s most stunning head-coaching changes. The Denver Broncos, Tampa Bay Buccaneers and New York Jets all had the playoffs in their sights before crashing and burning down the stretch. But another team that had a playoff spot in its grasp before falling short didn’t fire its head coach, to the surprise of many.

Loose lips don’t exist in Kansas City, not with Chiefs chairman Clark Hunt and new general manager Scott Pioli. But multiple sources around the league said Pioli signed a five-year contract that makes him the highest-paid GM in the NFL.

Call it the NFL’s version of global warming. This season’s NFC Championship Game in Glendale, Ariz., will be in conditions that are 91 degrees warmer than last year’s NFC Championship Game in Green Bay.

One way or another, Anquan Boldin was destined to play in today’s NFC Championship Game. But the question was whether it would be as a Cardinal or an Eagle.

Last spring, the Eagles explored the possibility of trading for Boldin, who wanted out of Arizona.

One of the offseason’s confounding issues is why coaches like Brian Billick and Jim Fassel can’t land head-coaching jobs — and why they’re even struggling to get interviews.

Billick’s work and accomplishments are well-documented. In his 18 NFL years, his teams went to the playoffs 13 times. He won a Super Bowl with Baltimore. Just as impressive, five of Billick’s assistants in Baltimore went on to become head coaches in one of the least talked about but most impressive head-coaching trees.

Despite a sprained shoulder that left Terrell Suggs questionable for the AFC Championship Game, the Ravens’ linebacker will play today in Pittsburgh.

Ending a whirlwind 24 hours in Tampa, the Buccaneers officially named Raheem Morris as their head coach and Mark Dominik as their general manager Saturday.

“Both of these men bleed Tampa Bay Buccaneers,” Bucs executive vice president Joel Glazer said while introducing the two promotions.
