IRVING, Texas -- The sun should not set again with Jason Garrett as coach if Jerry Jones isn't committed to him beyond next season, regardless of whether the Dallas Cowboys make the playoffs.

Either ride with Garrett or get rid of him. Anything else is a colossal waste of time.

Hey, the Jacksonville Jaguars fired coach Mike Mularkey on Thursday after one season, so it's not like there's some statute of limitations on firing coaches once the season ends.

Jerry made it clear he's the person calling all the shots with his soliloquy about the factors that led to defensive coordinator Rob Ryan's dismissal while taping his weekly TV show.

Monte Kiffin is considered the leading candidate to replace Ryan. Kiffin spent the past three seasons at Southern Cal coaching with his son, Lane, the head coach.

Kiffin's claim to fame is creating the Tampa 2 defensive scheme that involves playing the safeties deep and limiting big plays, forcing an opponent to drive methodically down the field.

The Cowboys' defensive assistants already have been told they will have to interview with the new defensive coordinator. If he chooses to keep them, fine. If not, they'll be unemployed.

There's also a possibility Jerry will yank the play-calling duties away from Garrett and hire someone else to call plays. Norv Turner, fired by San Diego, would be near the top of the wish list.

Whether Jerry hires Turner or someone else, that person will get an opportunity to add assistants familiar with his offense and philosophical approach.

Now, we're talking about the potential addition of two coaches who have considerable more loyalty to the owner than the head coach.

How dumb is that?
