This is reminiscent of our motto in the military;
No poly, no waiver, no statement, deny everything, admit nothing, and make counter accusations!!
The Big Ten rules about stealing signs seem to be you can steal signs but only in a manner we describe.
Is this the Lance Armstrong defense? Deny, then once it’s obvious, claim everyone does it?
The way this was handled looks like the Big Ten is out to get Harbaugh and/or Michigan.
