Well, now you're talking about NU's offense at its best. This team doesn't have those kinds of weapons and was never going to be a 2000 or 2005 or 2008 offense. They realized their limitations and formulated a game plan that played to the team's strength -- namely, defense. (And one thing to consider is that those teams played fast, which meant that NU's defense could be on the field longer when the offense doesn't score, and sometimes when they do.) I don't disagree that the offense could be MUCH, MUCH better. My point is that I don't think their record would have been any better. The losses would have been less ugly and the wins easier, but style points aside, I don't think they'd be better than 9-2.
If anyone thinks that Thorson this season is better than any one of those guys at their best, they're fooling themselves. However, you could argue that Thorson is better than they were as redshirt freshmen. That's what the argument, I'm guessing, was about. Kafka was abysmal in his first starts. Baz was actually pretty good (but awful as a sophomore and mediocre as a junior). Bacher and Siemian didn't play as RSF. Thorson's numbers are horrid, but that's a byproduct of the game plan, too. If he threw the ball as much as those guys did, he wouldn't be 116th in passing. His job is to hand the ball off, run it on occasion, throw when necessary and -- most importantly -- don't turn the ball over. He's done those things pretty well, and the bottom line is that his record as a starter is better than any of those guys.
So we'll see what happens with Thorson. I think he has better tools than all of them. We'll find out if he can develop the poise, decision making and moxie to go along with it.
