Since 1979, in the major sports: NFL, NBA, MLB, NHL, CF, CB:
The state of Michigan has 12 championships.
The state of Ohio has 2.
Ohio has an extra NFL and MBL team to better it's odds and to counter the fact that the Blue Jackets have not been in existence the entire time span.
In college sports, Michigan has two major schools vs. Ohio's one. Yet Ohio State does not suffer the same dilution of talent UM/MSU do within their own state, and thus would be expected to have a backyard edge toward winning championships.
The Tigers will soon make it 13 championships.
It's good to be a Michigander!
