re: Saban's replacement - who ya got?

What if, and this is a very large what if. Saban coached 5 more years and won 2 or 3 more Natties. Bama decided they wanted Kirby, and by then he was making 15 milion a year at UGA. Bama offers 20 million a year. I am not saying they would or that he would come, but it would be intriguing. UGA would have to match it would they not??
