Garrett, though, has failed to make the franchise anything more than average with a pair of 8-8 records since taking over during the 2010 season. In fact, no one has lately. Dallas is 128-128 since the start of the 1997 season and 1-6 in the playoffs.
"Ever since I've been in this league as a player, as a coach, I think everybody each and every day is playing and coaching for their jobs," Garrett said. "That's the nature of this thing and that's what makes the NFL great."
The Titans haven't had a great team since winning an NFL-high 13 games in 2008 when Schwartz was Jeff Fisher's defensive coordinator.
Munchak has been their head coach for just two seasons, but he almost surely has to have a record more like his first than his second to improve his shot to stay. The Hall of Fame offensive lineman led the Titans to a 9-7 mark in 2011 and slipped to a 10-loss season last year.
Titans owner Bud Adams, who turned 90 in January, fired chief operating officer Mike Reinfeldt at the end of last season. Adams allowed GM Ruston Webster to spend nearly $110 million signing veteran free agents such as left guard Andy Levitre and safety Bernard Pollard.
"I think in our mind we're on the right track and that's why I hope there's a lot of excitement," Munchak said. "The preseason games, I hope you'll see a spark and people will see what we're talking about. And, hopefully in September we'll see that change."
Oakland didn't make a change with its coach, giving Allen another opportunity with the perennially rebuilding franchise after winning just four games in his debut. Allen has little talent at his disposal because about 40 percent of this year's salary cap will be spent on bonuses to players who are no longer on the team.
"I know there's a lot of experts out there that might think differently, but I like this football team," Allen said last month.
Raiders owner Mark Davis, whose father, Al, ran the Raiders since the 1960s and died almost two years ago, has publicly backed GM Reggie McKenzie. He hasn't offered the same support for Allen.
A week after Carolina closed with a 7-9 record, Panthers owner Jerry Richardson decided Rivera would return for a third season. There's promise on the Panthers with Cam Newton at quarterback and Luke Kuechley at linebacker — both won rookie of the year awards in the last two seasons — but it needs to turn into production.
And quickly. The Rivera-led Panthers have started 1-6 and 1-5, but he's trying not to focus too much on how his possibly pivotal season begins.
"It's all about where you finish," Rivera said.
And if Rivera and his fellow hot-seat coaches don't win enough, they likely will be finished leading their franchises.
