Fitz needs to settle on an offensive philosophy. Personally, I think they need to go dual-threat at QB and run more option. You might not always get the best pure passers that way, but if you get the right guy at QB it makes your offenses harder to prepare for. If you look at the best offenses NU has had over the past couple of decades, it usually involved QBs who had some running ability. Even Thorson, who wasn't a great option QB, had some wheels and broke off some key runs on occasion. The ideal NU QB was probably Dan Persa, whose freak injury unfortunately crippled his career.
I just don't see a future for NU slogging it out in a ball-control offense in the B1G. That might work in the West IF you get a defense of the type they had with Hank for a couple of years, and that is probably the exception rather than the rule. I just don't think Northwestern makes a living trying to run over Ohio State, Michigan, and Penn State (or even Wisconsin and Iowa) year after year. And USC and UCLA coming in plus a complete realignment or even elimination of divisions isn't going to help. If you're going ball control, you'd better start recruiting a significantly higher level of RB talent.
