Are you sure about this? I seem to remember being upset at Saban because he waited so long to announce his leaving and Spurrier was already over at South Carolina
Wannstedt quit the Dolphins around the first week of November, in 2004.
South Carolina did not go to a bowl in 2004, so they were able to announce Spurrier as coach on November 23 of that year. It was only around this time that Saban even started to be mentioned for the Dolphins job.
If I remember correctly, for the latter half of that season, there was some speculation that Dolphins interim coach Jim Bates might get the permanent job.
There was no opportunity for Saban to announce he was leaving, in time for us to get Spurrier before South Carolina did.
