My first real favorite at Bama was Joey Jones. I was just old enough and watched/listened(mostly) to enough Bama football to understand everything. He was an amazing WR given his natural limitations. He also gave everything, everytime to make some pretty spectacular catches, one handed with one toe inbounds. If he played in the replay era, I think he would have many more catches to his name.
There are certain players that have always been favorites for me. The guy that isn't a 4 or 5 star talent but gives everything they have for Bama and makes some spectacular plays or just plays through adversity and/or pain. Nobody epitomizes that more, in the modern era, than Lane Bearden. That dude will go down in my list of Bama Badassses forever. Javy is on that list, some physical limitations and almost quit the game because he thought he did not have what it took but he blossomed into an amazing player for us.
There are others like those three above but I think those three are my three favorites ever. There are many others that I liked for what they did with their tremendous talent, Derrick Thomas being my favorite of the studs.
