You can also blame Nick Saban. Even at 1.7 million, Croom was the tenth highest paid HC in the SEC, tied with Houston Nutt, and only ahead of Bobby Johnson at Vandy.
Not giving him a raise after the Liberty Bowl would actually send the message that we aren't that serious about football because then the media would say "Here's a coach that just won 8 games for the first time in five years and he doesn't get a raise. What kind of football program is this?"
Besides, signing Mullen for 1.2 instead of the rumored 3 million pays for over half off Croom's buyout initself because Byrne saved us 1.8 million.
