I think people fall into one of two camps. Those that look at the personality and coaching success vs the pure stats and success side. Neither is right or wrong, but will never line up.
Johnny made Iowa State a basketball school, but it wasn't necessarily because of the results on the court come the end of the year.
Tim Floyd was an excellent coach but his personality was stiff and he just wasn't here long enough.
Larry had arguably the best start of any coach, but that was by inheriting a ton of talent and he trailed off a bit as the time went by. He was very likeable but also gave us a huge black eye.
I refuse to acknowledge Morgan.
GMac was a wonderful person but didn't get any results.
Fred had the charisma and early success. People loved him almost as much or as much as Johnny. He had both success and personality, but he basically stopped aggressively recruiting the last 2 years and others were catching up with the transfer concept. I think his success was less about X's and O's as it was finding the right players at the right time.
Prohm had a lot of talent go through the program with arguably mediocre results relative to said talent. One can make a good argument his success was because of recruiting rather than coaching, but that could also be false.
TJ has the charisma and personality above all but Fred and Johnny. His true passion for the school makes up for any of that and gives him a leg up on others. He's also a beast of a recruiter and was responsible for much of the talent prior to his HC time. He took over a 2-22 program and despite that and all the headwinds in CBB has the 2nd best winning percentage in ISU history. Those results might not have the height of TF or LE just yet, but his coaching job was arguably much, much harder given the circumstances, state of the program, all time height of the Big 12 in basketball, NIL disadvantages, a barebones cupboard, etc.
So in my eyes, arguments can be made for many when looking from different angles. However, if you consider what he took over and has had to swim upstream against, TJ has done arguably the most amazing job of coaching, program rebuilding, and getting the most out of his players as anybody before.
