It would be cool to have a Heisman/Pro-Style QB go off as Keller is hyped to do. It would be even cooler (sorry for lack of colorful words) to have him throwing to an NFL prototype receiver.
However...
1) To put up huge passing numbers, you take away from what is an obviously strong running attack we have returning. Big numbers by QB's and WR's doesn't equate to wins and championships (ask T-Tech, Hawaii and New Mexico State)
2) Our offensive line has some SERIOUS work to do if our passing numbers and efficiency are going to grow any further than they are right now. But again, if they are solid, a balanced attack would be the best result in my opinion.
We have made huge leaps over the last season offensively. But if our offensive line jells, and we start getting better production out of our tight ends, what we have seen this season is nothing. This offense has the potential to put up huge numbers, striking from almost any part of the field. We are just a couple recruits away.
I was noticing last week that we were starting all underclassmen. The only upperclassmen that have really contributed this year are Mann and Austin and maybe Carl Nicks if you want to count him. With both of Mann and Austin out the younger guys have only gotten more experience. This line could be awfully good in a year or two.
Couple that with the running backs we've got and some young tight ends and receivers and all that's missing is a talented quarterback. I really really hope that Keller and or someone else steps up and delivers because with the pieces around them they could really put the NU offense on the map. I see a lot of promise for the future on offense.
