You make it sounds like 4 in a row with all-time greats is a knock against Smith. Literally no coach has won more than 4 in a row since the scholarship limit changed to 9.9. Not even Cael and Gable. And 4 titles alone would be good enough to be the 3rd best NCAA program of the past 50 years behind Iowa and Penn State. No program outside of those two have won 4 or more total titles in the past 50 years. OSU only won 3 outside of this dynasty.
All coaches in the 9.9 scholarship era with multiple NCAA titles won at least back-to-back titles followed by a drought. The only ones that were able to win more than 1 outside of their big streak was Gable and Sanderson. Brands won 3 in a row with an all-time great recruiting class followed by an 11 year drought before getting his 4th. Zalesky won 3 in a row and then never again. J. Rob was back-to-back titles and 5 years later after OSU's dynasty won another.
Smith is literally the 3rd greatest coach of the past half century. He's 5th all time in individual national champions with 33. Only Gable (45), Nichols (38), Gallagher (37), and Cael (34) have more. It's a rate of more than 1 per year, which is better than Brands, better than Jay Robinson, better than Rob Koll, better than Bobby Douglas, better than Tom Ryan, better than any PSU coach outside of Cael, better than any Iowa coach outside of Gable. Only 5 programs have more individual national champions than Smith has coached (OSU, Iowa, ISU, OU, and PSU). It's more champions that storied programs like Lehigh, Minnesota, Michigan, Cornell, and Ohio State have in their entire history.
Smith has coached 150 AAs which is 3rd all time behind only Nichols (156) and Gable (152). It's an average of nearly 5 per year (4.84). It's more AAs than in the history of Cornell, Illinois, Wisconsin, Arizona State, and Nebraska.
