If Larry Brown is indeed on some "one hit wonder" list, it's just the residual lingering of the usual anti-Cowboy "asterisk" crowd just waiting for the chance to pounce on any accomplishment.
I remember the very night after Dallas beat Pittsburgh's *** in that SB, the talking heads were just stumbling over themselves to give the ole' "Dallas didn't win this, Pittsburgh LOST it" drivel. And Browns two INT's were the "poster boy" for all the blowhards.
Where's Desmond Howard on that list? Guy never did squat his whole career except in the SB game for the Packers. Doug Williams? Trent Dilpher? Mark Rypien? Even Joe Namath...........you could make the case for even him being a "flash in the pan" more than some "long term" great! Like Ali, his big mouth and bravado counts for about 75% of whatever "legendary" athlete he is.
No, there's about 500 guys ahead of Larry Brown on ANY respectable lists of "one hit wonders"..............if there's even such a list worth repeating.
