I don't know how much explanation this really needs. Everyone has the Jekyll-and-Hyde archetype in their minds.
Alright, well, maybe not everybody. So for those who need a refresher or whatever, Dr. Jekyll was the name of a really good college basketball team from back in the day. Mr. Hyde was a really bad college basketball team. But get this: They were the same team!
I'm nothing if not highly literate and literary. I celebrate that spirit today by reviving the plot of this old novel about college basketball by listing the modern-day teams that most closely fit the Jekyll-and-Hyde mold established many years ago.
