Scout, Lyon actually ended number 2 on the all time list behind "Scooter" Edwards. At the beginning of this season Wooden had 4,213 yards. Lyons had 5,499 and Edwards sit on top with 6,553. Not sure how many yards Wooden has racked up this year but he will probably wind up ahead of Lyon. I think it would be a stretch to take the #1 spot though.
