The head official obviously has a brain fart and needs a second opinion and the 2nd official can't give it. You almost have to blame the 2nd ref in this situation. The head official is trying to make the right call but with the feeback from the 2nd official only gives the one for escape.
This is something I would like to see high school official's doing more of. Confirming close points with the other official on the mat if there is one (Obviously does not work in this case).
I can see where Michigan could have gotten 1 and 2 or just 2. Could go either way, no bad call on that end.
