Not really. Jackie was good. Then we went down when we were on probation. Croom wasn't a great coach but he did get us to the Liberty Bowl and should have won more than he did. Dan has been successful as well. Take away the probation and who knows how the 2000's go?
Lots of historical factors as well- integration, SEC expansion, rise of the power five conferences. You can't compare 1940 MSU with 2017 MSU.
