To date, the barn has now fired their last 6 head coaches. Dye was the last one who actually resigned on his terms
		
		
	 
And in all honesty, Dye would have been fired had he not resigned. That whole charade was to get the NCAA to not hit them too hard for the Eric Ramsey scandal.
Then again, Mike DuBose was going to be fired had he not resigned, too. 
However - as others have noted - it's always amusing that ALABAMA gets the bad rep as the school that chews up coaches and fires them Steinbrenner-style and yet that has never been true. 
Prior to 1911, coaches at all schools 
generally were senior players who coached one year. In the last century - going back to Xen Scott dying while the coach - Alabama has only "fired":
- Ears Whitworth
- Mike Price
- Mike Shula
Now granted, Red Drew stepped down because of a loss of confidence in him and DuBose would have been fired had he not resigned, but the reality is that we don't have near the history of reflexive throwing the captain overboard that people like to allege. 
Ray Perkins, Bill Curry, and Dennis Franchione all resigned and left at the height of their popularity on campus. One could argue so did Wallace Wade.
Frank Thomas took ill but remained the AD and Xen Scott died. 
Bryant, Stallings, and Saban all retired never to coach again. And as I said, you can't "really" count the coaches prior to 1911 because you didn't have coaches in the same sense we do today. But the brutal fact is we've had just as many retire (3) as we've fired (3).
