After this past season, a third of the NFL changed coaches. You would think that cooled the seats of the remaining coaches, but it didn't. Owners and fans are impatient. They want winning seasons and playoff contention.

Here are the five coaches who are on the hot seat heading into the 2009 season.

1. Wade Phillips, Dallas Cowboys -- Owner Jerry Jones loves having Phillips as his coach. With Phillips in charge, Jones doesn't get the tension he had from Bill Parcells, who always was making demands. Phillips is a players' coach, and the Cowboys have a nice environment. But the Cowboys are moving into a new stadium, and Jones wants to win. Phillips has been around long enough to know a coach is on the hot seat every season, so this doesn't come as a surprise. The Cowboys have enough talent to be a contender. The pressure is on.

2. Jack Del Rio, Jacksonville Jaguars -- Jags ownership made major changes during the offseason. It promoted Gene Smith to general manager. In doing so, it gave Smith the authority to pick the 53-man roster, a role usually reserved for the coach. Del Rio now is one of only a few coaches in the league who don't have that power. Any coach who loses power in any regard knows he is on the hot seat. Del Rio has been more vocal this offseason in challenging veteran players such as John Henderson, another sign he's feeling the pressure.

3. Jim Zorn, Washington Redskins -- Any employee of Dan Snyder knows his job is on the line each year. Snyder wants a winner. He's willing to give an employee all the necessary resources. He signed the league's top free agent, defensive tackle Albert Haynesworth. He paid big money to keep DeAngelo Hall and bring back Derrick Dockery at guard. Zorn has to produce.

4. Gary Kubiak, Houston Texans -- Owner Bob McNair is a patient man, but it's time for the Texans to get over the 8-8 hump. McNair realizes how difficult that is in the AFC South. The Colts usually win 12 games, and the Titans' Jeff Fisher is hard to hold to fewer than 10 wins when he has the talent. Kubiak has done a nice job of turning around the Texans' roster, but it's time for Houston to take the next step.

5. Dick Jauron, Buffalo Bills -- Jauron is in the same situation as Kubiak. The Bills have been stuck at 7-9 seemingly forever. To break from that rut, the Bills signed Terrell Owens to open up the offense. If that doesn't work, it could open up a coaching opportunity in Buffalo.
