Yeah where Cody Green went i wouldn't call a big name university. Berringer also played with a partially collapsed lung for like 3 games and went out against Kansas St. Berringer could pass. he was more of pro-style qb than a running qb. Yes Berringer didn't wow because he was a backup. He didn't play that many games compared to Martinez so he wouldn't have had the chance. Those games were close but in the 4th quarter we pulled away. the closest one being OU 13-3. It's not like they were 3 point games at the end.
Berringer did not go out against Kansas St. His lung was injured against Wyoming. That game was the only game all year where teh offense basically had to bail out the defense, and Brook played very well. It was the next week against Oklahoma St, where the offense was horrendous in the first half, lead 9-3 at halftime, and were thankful to be ahead thanks again to the defense. Brook did not play in the second half of that game. Matt Turman "played" qb in a 32-3 win. It was the defense, oline, and Lawrence Phillips that won that game. Turman started the game the next week against Kansas St. again, a game won by the defense, oline, and Lawrence Phillips. Brook was then pretty much fully recovered by the week after against Missouri, and basically 100% by the following week against Colorado. Hence, Brook did not play 3 games with a collapsed lung. He played maybe a full game total in a 3 game stretch with that injury.
As far as pulling away in the 4th qtr, yes, that is also part of the point here. Berringer never did anything to wow the team to a big early lead. It was the defense that had to carry the team. Only against really bad Missouri and Kansas teams did Nebraska control the game start to finish.
I really cant believe I'm making this argument. I feel I'm being incredibly disrespectful to Brook and I apologize for it, but I'm just trying to make a point based on facts. I just dont see where Brook can be considered an all time great qb at Nebraska if you base it solely on his on-field play.
