I don't know if Arizona was ever a leader, but they're no longer on his radar. It was believed UCLA was the favorite b/c of Neuheisel/Chow. Brehaut has apparently committed to the Bruins, however, so I'd guess they're out. He trimmed his list to 8 this week.

I think this kid is a little better than Harrell, but opinions vary. I know Heupel has painstakingly evaluated every QB across the country and decided this kid was 'the chosen one.' I think he's one of the best all-around QB's available.
