Both were completely passed up for jobs that both seemed pretty logical for them (Bama for Jackie and Florida for Mullen). The common story is that Jackie never even got a phone call so he could have the opportunity to say "thanks but no thanks," and I'm beginning to think that was the case for Dan Mullen as well, even though many were saying the job was his to turn down. Might he have gotten a little miffed over the rejection and it's stewed in him over the last several months?
