We'll see how many opening there are. Saban refused to answer any questions about Alabama at his press conference.
Some sources are already claiming that the Bama offer is official. Considering that Bama became a national joke after the Rodriguez mess, I think they may have landed Saban. After all, they wouldn't want to repeat that tragi-comedy (with Saban this time around) all over again.
Miami Herald mentions a 40 mil. official offer: http://www.miami.com/mld/miamiherald/sports/16362536.htm
