When I first read that Marty Schottenheimer passed on a 1-year, $4.5 million extension including a $1 million buyout, I didn't really understand it. The San Diego media couldn't either. 
Schottenheimer will return to coach the Chargers in 2007, but only for the final year of his contract.
With some time to think about it (and watch NFL Network), I think he passed on a guaranteed $1 million for a few reasons.
1. The offer was a slap in the face. We should all be so lucky to have $1 million slaps in the face, but coaching contracts are guaranteed. It's my understanding that a buyout in the NFL is nearly unheard of. The Chargers weren't really committing more than next year to him.
2. Schottenheimer is 63 years old. Coaches lives are year-to-year, especially at that age.
Those two reasons are fairly inarguable. The next two are my own takes on the matter.
3. Schottenheimer probably feels confident he can win next season. If he wins (in the playoffs), they will pay him even more. And maybe he'll be able to force GM A.J. Smith out of power. If he doesn't win, even Schottenheimer will know it's time to move on.
4. If the team is in turmoil next season, it won't be a pretty situation. But I suspect Schottenheimer knows it could be a subtle rallying cry for his players. They all seem to love playing for Marty. Intensity is never a problem with the Chargers. That's why Marty wins in the regular season. In a way, Schottenheimer will be closer than ever to his players.
An NFL player always exists year-to-year. Their contracts aren't guaranteed. Now the Chargers coach will be in the same boat.
Other coaching news
Here's where we stand with the remaining vacancies
Pittsburgh - They finished second interviews with Vikings defensive coordinator Mike Tomlin and Steelers offensive line coach Russ Grimm. If the Steelers don't announce their choice by Friday, Bears defensive coordinator Ron Rivera is probably the pick.
Miami - Cam Cameron, Chan Gailey, and Jim Mora have all had second interviews. Mike Shula is also a candidate, but probably a longshot. A decision is expected Thursday or Friday.
Oakland - Reports that Chargers WR coach James Lofton was expected to get the job proved premature. USC assistant Steve Sarkisian met with Oakland for a second time Wednesday and is believed to be the favorite. Patriots offensive coordinator Josh McDaniels is a darkhorse.
