Good analysis. I didn't mention any of the CBs because BYU doesn't produce NFL quality CBs. They have produced safeties, LBs, and DLs. I can see Jorgenson getting drafted and perhaps another as you mentioned. Of the LBs, there's Nixon and So'oto, given their athletic skills.
Pendleton and Clark might end up on a roster somewhere if as you say they show they have the mental ability.
On offense, there is alot of talent. George will have to prove himself, but he'll get two seasons without splitting time with So'oto anymore to do so. I am still not convinced Unga has NFL speed, but he is fast enough and elusive enough to be given a shot. Fui and Tonga will get some serious looks I agree.
It will be fun to see what comes of these players if the team performs as we all hope and expect.
