This deserves its own topic. No one had his combination of speed and talents. When he was injury free, he was a special talent.
And he did pay a terrible price to provide us enjoyment. Props to him, he will forever have my respect.
Since 2000 here is how I rank them.
1. Luke Staley
2. Jamaal Williams
3. Harvey Unga
4. Curtis Brown
And Luke is the best of all time here at BYU.
