JACKSONVILLE, Fla. – The more Jacksonville Jaguars owner Shad Khan watched his team play, the more he realized one thing:

“We needed a rebuild from the ground up,” Khan said.

So the Jaguars fired coach Mike Mularkey on Thursday after just one season, the worst in franchise history. The move came 10 days after Khan fired general manager Gene Smith.

Khan also introduced new GM David Caldwell on Thursday, and by parting ways with Mularkey, gave him a clean slate heading into 2013.

“I bring a track record of success,” Caldwell said. “I’ve never endured a sustainable losing team.”

But maybe the biggest nugget came when Caldwell said New York Jets quarterback Tim Tebow is not in the team’s plans.

“I can’t imagine a scenario where he will be a Jacksonville Jaguar,” Caldwell said.

Mularkey, who went 2-14 this season, is the eighth head coach fired since the end of the regular season.
