I care. I want a Super Bowl. No coach has ever won a Super Bowl with two teams.
You can talk all about how great a coach someone is but at its heart, the strategy you're talking about has never worked. Everyone thinks "Oh, this guy won a SB. He must be a great coach. If we get him, we're that much closer to a SB ourselves." The problem is, that it's just not true.
1. Vince Lombardi - Finished with the Redskins, 1 not so great year
2. Hank Stram - Went on to 2 bad seasons with the Saints
3. Don McCafferty - Went to the Lions and finished 6-7-1
4. Tom Flores - Went on to 3 bad years with the Seahawks after winning 2 SBs with the Raiders
5. Mike Ditka - Went on to 3 bad years with the Saints
6. Bill Parcells - Took the Pats to the SB but lost, took the Jets to the AFC Championship, and the Cowboys to the playoffs
7. George Seifert - 3 not so great years with the Panthers
8. Jimmy Johnson - A few playoff appearances with the Dolphins
9. Mike Holmgren - 10 years at the Seahawks and made it to the SB once but it took a long time
10. Dick Vermeil - Some good years with the Chiefs
I don't want Gruden and I don't want Cowher and I don't want Dungy. I think they've got fail written all over them. If we're going to switch coaches (which I think is a huge mistake), then I want either:
1. some great coordinator/assistant coach who's a rookie HC and I want to give him a few years to get everything together or
2. a coach who got to a SB with another team and lost or
3. a coach who built a powerful team but didn't make it to the SB
Because THOSE are the coaches that win SBs. Not retreads.
I like how you think.
"Must Spread Rep"

and when you think about it, is there ANYONE who won Super Bowls with two different teams? If there is, I'll bet it's a real short list.
