The first famous bad Heisman vote was Paul Hornung in 1956. The fabled Irish went 2-8 that year, with Hornung throwing for 3 TD and 13 INTs, while averaging 4.5 yards per carry.
Syracuse RB Jimmy Brown, Stanford QB John Brodie, and about a dozen other players have a better claim to the Heisman that year.

Archie Griffin's 2nd Heisman was BS, imo. It was objectively a big downturn from his 1st Heisman season, and several other RBs at P5 teams had much better seasons.
.
In my living memory, Ty Detmer's Heisman was BS, in 1990. If you wanted a big-numbers G5 QB, Klingler's numbers were superior. If you valued excitement, Rocket Ismail finished 2nd, but for all his flash, he only scored 6 total TDs.

People seem to have an issue with Chris Weinke, but who are you putting ahead of him? Heupel and Brees (2nd and 3rd) had worse years than him. Tomlinson had a great season vs a high school schedule. Honestly, 5th-place NW RB Damien Anderson probably has the best case.

I would've taken Ki-Jana Carter over Salaam in '94.
Rex Grossman would have easily won in 2001 if he hadn't been a sophomore.

Jason White won the Heisman because his closest competition was a WR (Fitzgerald) and voters were idiotic sheep.
