6'3", 245# OLB/DE - 4 star ranked #21. Is praised for his speed, size and aggressiveness. Received and offer from a lot of Pac schools, Clemson, Oklahoma, LSU, etc.
There's always that risk but a verbal is just that...a verbal. The player has expressed his word to play for Oregon. I'm not a math guy, but I would estimate this usually means the player ends at Oregon 95% of the time.
If we're looking at it the glass half empty, players, after signing LOI are more likely to not qualify or leave Oregon for personal/health reasons than they are to back out of a verbal -- but, it's always a possibility.
