Hands down? By what metric do you rate Lou above Harry? Harry had a better winning % (.678 vs. .654), more B10 titles (4-1) and more final fours (3-1). Harry coached Illinois for 20 years vs. Lou's 21.
Your profile pic looks like Harv Schmidt. Harv played on some very strong teams under Harry.Harry and Lou are big reasons Illinois is #11(12?) of all-time top college basketball programs.
Side note, Harry was a phenomenal coach at Champaign high school prior to the Illini years.
That's changing. I picked Underwood because I believe that when he retires he will be known as Illinois greatest basketball coach.
