The logic behind keeping or firing an NFL coach isn't always reliable, but Black Monday is always busy. Some gut reactions to this year's opening offseason moves:

1. Eric Mangini, Cleveland » He saved his job a year ago with a four-game run to end the regular season. Back-to-back wins against New Orleans and New England came a little too early this year, and his fate was probably sealed before Sunday's blowout loss vs. Pittsburgh.Deserved to go

2. Tom Coughlin, N.Y. Giants » The hardest thing about firing a coach is hiring a new one. Even though the meltdown against Philadelphia was horrific and the loss at Green Bay ultimately proved devastating, the Giants would've lost even more by ditching Coughlin. Deserved to stay

3. Leslie Frazier, Minnesota » Similar to Coughlin, the Vikings, both owner Zygi Wilf and the players themselves, are comfortable with Frazier. The removal of his interim tag was the least of their problems in a season gone very wrong. Deserved to stay

4. Jason Garrett, Dallas » The guy went 5-3 with a team that was 1-7 when he took over. He was hired independently and before Wade Phillips. Although the Rooney Rule requires the Cowboys to interview a minority candidate, Garrett has always been the guy. Deserves to stay

5. Jack Del Rio, Jacksonville » He's been on the hot seat for the last three seasons -- all of which the Jaguars have finished by missing the playoffs and none worse than this year's three-game slide when the AFC South was theirs for the taking. Del Rio has one playoff win in eight years. He'll get a crack at Year 9, but we disagree. Deserves to go
