Here is an excellent article by Even Woodberry on the ability of and ramifications of Auburn firing Tuberville.  In the article he discusses how Tubbs has won all his previous battles, buyouts, irrational fans (boosters and radio show callers) and while he doesn't explicitly say it, how Tuberville, given his success over the last 4 years is esentially in a win win situation, while Auburn could easily be in a lose lose situation.  Sorry to recap the article but I had to get the post to 75 words.
