I quite disagree on your assessments of talent levels....
I went over BYU's 22 deep. Please understand. If you think BYU's players are at or below average then you have been fooling yourselves. That program is defiantly about average in the running back spots after loosing a 3000 yard back to red shirt, but the O Line is healthy, large and physically impressive. They did not dominate Texas' #3, #5, #15 #10 and #21 recruiting classes because they can't play.
RECEIVER GROUP
All run 4.5 or better. FYI 40 x's are often misunderstood. Little 4.3 guys in pads are usually slower than big 4.5 guys in pads. Long legged guys take fewer strides to cover more ground. BYU' main outside X and Z group go 200-215 lbs and stand 6-6-1/2, 6'-5-1/2, 6'5, 6'4, 6'3, 6'2 and 6'-1. The hybrid H/Y receivers go from small 5'9 4.4 guys to true Y slots who are 6'5 and 6'4 respectively. The 3rd string Y is 6'1 and a 4.39 guy. BYU has the tallest and one of thd fastest receiver groups in the country. You are kidding yourself if you think these are really just 2 star kids. I spent some time braking them down on film. Fast, tall, great hands. They are at receiver group 3 deep in 4 positions what USC wishes it was.
Linebackers... They were young, did not play well as a unit last year. Too much free lancing, not enough duscipline. But talent was not an issue. The add several newbies this year including a walk on that turned down full rides at Purdue, Houston, aTm and most Texas programs. He has already made the 2 dep as a freshman, runs a 4.5 40, is 6'4-1/2, 227 and tackles like a freight train. He will play behind a 4.55 guy. The first 4 MLB'S are 4.6 or faster, 6'1, 6'-3, 240-245 types, much more disciplined this year. The other to OLB on the Weak side are 6'4-225, Kyle Van Noy type and 6'4-246 (both NFL 4.5 40 types). These guys would play in the B1G, PAC or SEC.
I am not going through every position group. We know Nebraska has quality players in most positions as well. I just think a lot of Nebraska fans are making the mistake if thinking BYU is a little better than Wyoming or Northern Illinois. That is not the case.
They are smart as well. Their SINE is nasty. Two of last year's starters are 2nd string this year they have developed so much more depth. 5 of their first seven defensive lineman are Polynesians...hard nosed dudes.
Again, I predict Nebraska wins. Been saying that all along. But the opponent here is better than most of the rest o DC the teams on Nebraska's schedule, especially on offense. Lincoln is a big benefit. But BYU has won some big games on the road as well. Just say'n.
I've spent 33 season as a FB writer. They are a big time program, not Iowa State or Southern Miss. The star ranking are poof and made for fan fodder and advertising sales. It's not that meaningful in terms of why teams really win. But skating that mythological dragon is impossible. Fans will believe the absolute crap fans want to believe.
