No conspiracy...just poor judgement on ESPN's part. Instead of reporting and commenting on football, they ran a campaign to get Woodson the Heisman Trophy. I don't think it was anything against Tennessee, just that they thought it would bring variety to the Heisman race by having a defensive player win it. Unfortunately for UT fans (and for the integrity of ESPN), Peyton Manning was left out. That is simply an injustice and an embarrassment for one of the greatest QBs of all time to get beat out by a very good defensive back. I do recall watching more than one Michigan game in 1997 where Woodson was burned for long TD passes; however, when SportCenter ran highlights, they conveniently failed to show those plays. They did someho manage to show Peyton getting intercepted. Yes, ESPN's campaign for Woodson was the reason Peyton didn't win the Heisman.
For Tennessee to be one of the winningest college football program for the past 75 - 80 years (we used to be #1), I find it curious as to why we haven't won the Heisman a single time. Compare us to similarly successful teams and name just one other team in that group that doesn't have one (I haven't actually looked...just guessing). Johnny Majors was beat out by Notre Dame's Paul Hornung who led the Irish to an impressive 2-8 season. Heath Shuler came close, but probably didn't deserve the Heisman. And then there's Peyton Manning.
I'm sure that in retrospect, ESPN sees that they erred in the selection of "their" candidate. Too bad it was at the expense of such a great player and person as Peyton and to a lesser degree at the expense of the University of Tennessee.
