re: Has any program ever taken a dive after winning a natty like Ole Miss baseball?

lol Well, I don't know if you are wanting to keep this in the realm of baseball, but after the LSU football NC in 2019, which, according to most LSU fans was one of, if not, THE best cfb teams of all time?....the following 2020 season turned into a steaming pile of goo in a burning dumpster and ended up 5-5. I wouldn't even call that a 'dive', in fact, I'm not sure there IS a name for that kind of collapse in college athletics.
