Since you think you've made a point...
...I want to get rid of coaches faster than most. So, if MM goes with DB next year, and the team has the same sort of year (8-8 or 9-7, misses the playoffs because of DB's poor games), then yeah, I'd say that MM's on the hot seat. This is the NFL, and it stands for Not For Long if you don't learn from your mistakes. And "being on the hot seat" means you get one more year to prove otherwise. If MM stuck with DB for three years, the team never makes the playoffs, and it's because DB stunk, then both should be shown the door. I have a feeling, though, one or the other won't make it that far. And I bet you know which one I mean, too.
