I know one is their linebacker Reid (Reed?) and is the other a D tackle?
Utah has enjoyed an over-inflated reputation due to some very exceptional defensive showings and a weak p12. That defense is still capable of being very good.
The offense is another matter, but they're also not as bad as they looked this last game because Rising will be benched and Wilson will play; and he will continue to get better. They have a really good oline and bernard has become a really good back. They do have a couple of good receivers in parks and singer, but Wilson will still be making freshman mistakes. I also think it will be important to present him with confusing alignments, hit him a few times, and just keep him uncomfortable as much as possible.
Plus, maybe Whit actually has learned from his last two games that they're not world beaters and they better take points every chance they can, rather than be all cocky and go for touchdowns on 4th down. (Btw, I was glad to hear KS after the game say he knows he should've kicked that field goal on the first drive - going for it was a bad call, even if they had scored a touchdown it would still have been a bad call imo.)
Sum up - utah will be out for blood, they're generally well coached, could have important defenders back, and BYU won't be playing a hampered Rising. I do think BYU can win the game, but imo it's shaping up to be the hardest game to win of the season.
