Sam did say that he was a little more lenient than others when it comes to the O-line, and that the memories of the 90's O-lines cloud the perception of fans. Benning agreed that the fans are biased and only want to remember the 90's linemen.
I always find these remarks interesting. First, fans are always biased. But, second, the reason fans get hung up on the 90's is because it's players like Benning, Jason Peter, etc., that use the 90's as a point of reference for just about everything they talk about. This is what those former players know, of course, so I'm certainly not saying they have to use difference points of reference because that'd be just ridiculous. But the fans and former players feed off of one another when it comes to 90's references, and like I said, I think a lot of that has to do with the fact former players and analysts regularly use the 90's as a point of reference.
IMHO that's the standard Nebraska should be held to. Maybe not THAT dominant, but at least in the same realm. That's why I don't have a problem using the 90's or being biased towards them. Any team should strive to do things the way we did, the way Alabama is now.
