Almost as silly as that stretch armstrong analogy (yeah I went there)
Let's have some fun with this; here's some names that probably wont ring a bell for the average fan as time has passed but they all have a common factor in being head coaches that lost the Super Bowl. There's also a good chance I went back too far starting with the '80's but what the heck.
'81 Forrest Gregg, Bengals
'85 Raymond Berry, Patriots
'94 Bobby Ross, Chargers
'01 Mike Martz, Rams
'02 Bill Callahan
'12 Jim Harbaugh
Maybe recognizable, maybe not, point is no one cares about the losing team. Everyone remembers the Champion (the exception, of course, being Bill Belichick who choked on 18-done or possibly Mark Levy who lost four straight)
And didn't they all go to another team and bomb miserably.....good list, much better than mine, I put him in with hall of famers which is not realistic at this point in his career ....
