First off the NCAA is a joke and the way they handle things, decisions seem to be inconsistent and normally you don't know what to expect.
My GUESS is the NCAA already informed Martell and Miami and Martell and his lawyer immediately on the spot filed an appeal on the decision , thus creating the delay. Maybe even an immediate lawsuit was filed.
The NCAA announced nothing as its under appeal or even a lawsuit and Martell and Miami has leaked nothing. Too many crickets right now and this is taking way longer than normal. Just a thought, this is complete BS.
