OSU-Central Michigan finish

But it didn't satisfy the requirements to call it intentional grounding.

Maybe not, but I thought you were making a distinction between an illegal forward pass and intentional grounding. IG is a form of an illegal forward pass. Many don't know this, especially as it relates to using this rule instead of an illegal touching foul -- when there is no eligible receiver in the area and the QB throws it to a guard or tackle. If the QB is still in the pocket or the pass doesn't cross the line, the correct call is illegal forward pass rather than illegal touching.
