What was Mosca talking about?

During halftime, Mosca was talking about the 72 reunion dinner and someone not being there or someone not being invited.

Does anyone know the back story?

It was “possibly” about Darren Flutie not attending.

I think it was about Bob Young not being invited to the dinner. Ang is very close to Bob, as it was Bob who brought Ang back into the organization and encouraged him to write his autobiagraphy.
