You do not need a teaching degree to be a professor.
Most universities are private institutions, and can employ whomever they see fit in whichever positions they seem appropriate. They have a vested interest in employing accredited individuals.
What I am saying is Florida will run out of such individuals at which time, it will become very easy for anyone to become a college professor.
Also, I have been a college professor, and I only have an undergrad. Not in teaching. It was my actual title.
