The idiotic argument is usually the one that is misinformed. Stevenson didn't replace Matta, Todd Lickliter did. Stevenson didn't coach at Butler till a full six years after Matta left. I never claimed it was impossible for there to be better coaches than Matta, just made my argument against what I see is illogical judgment of him. And if you're going to use the OSU went to the elite eight through luck argument, then I think you should know that during both those championship runs Butler won in the second round by 2, and in the 1st round by 2 in close late game situations. Every team in the tournament that goes far does it somewhat through luck, it comes with the format. I'm just saying that if one looks at the history of OSU's program, it is pretty unlikely we would find a coach capable of getting them to a higher level of success than Matta.
I think you should also know that all these coaches that had success after Matta were tutored underneath him as assistant coaches, but I guess given your argument these coaches learned nothing from Matta and Matta deserves no credit in helping them be in the position they are today.
Even the coaches you're comparing him to like Izzo, Self, Calipari(funny that you argue Matta needs 1st rounders then mention Calipari who has an entire team of them), Pitino , and Ryan who are probably all top 10 or near top 10 coaches, have had similar struggles. Since you mentioned early exits, Izzo has been eliminated in the 1st/2nd round 6 times, Ryan 7 times, Self 4 times, Calipari 0 times(though there was an NIT year), Rick Pitino 3 times(1 NIT year). It isn't like Matta has the best program or best talent brought in out of all these coaches either(especially in the case of Kansas and UK). I'm not saying he is better than any of those guys, but those are top tier coaches and his numbers are comparable(even favorable) to some of them with OSU.
