Pelini needs to figure out exactly what he wants to accomplish here, and set up the offense/defense to accomplish that. Once that is done, he can go out and recruit the guys that best fit what he wants to do. They want to be smashmouth? Go out and recruit the hell out of the biggest and baddest Olinemen in the country, redshirt them, get them in the weight room, and by the time they are jrs/srs, let the pipeline roll. Go after the best rbs. If they want to run some type of finesse offense (which I really don't care as long as it works), then go after fleet wr's and gunslinger qb's and pass protecting Olinemen.
Right now, it just doesn't seem like NU knows exactly which direction it wants to go, but I think they're on the right path. Give it some time fellas. If we're chatting with our family after thanksgiving dinner in 2014 about these same issues, then we've got problems. I have faith in Pelini, always have. He'll figure it out.
