Missouri would have been a good one. With 6 million pairs of eyeballs, and bordering 2 B1G states that would have been much better than Nebraska , in the long run. No question.
Pitt wouldn't have been bad either. Although with the state is already wrapped up with Penn State, not much would have been added in the eyeball department.
New Jersey has 9 million people. And is just across the river from New York & another 8+ million. That's a lot of eyeballs to gain.
Rutgers had to commit to improving their facilities to join the B1G. That is happening. Build it and they will come, right? It's possible. Turn any of their programs around and they will have the people to fill the stands. All it takes is one not-so-good coach to ruin a program(see previous Iowa bball coach), and one very good coach to turn a program into a success (see current Iowa bball coach). It can happen with the right hire. Just ONE hire. You simply need to look towards Iowa City for examples.
Want another? Manhattan, Kansas... Bill Snyder has made something out of nothing in lil ole KSU. And he did it TWICE. Imagine a coach like Bill at Rutgers, 40 miles from the Real Manhattan. Tell me you don't see dollar signs $$...?
