I like your optimism, but given the length of time with no official statement, my guess was his initial request was declined by NCAA and currently in an appeal process. As far as I can see, not a lot of transparency on the waiver process, so it is anyone's guess as to what criteria they are considering. Fingers crossed Mballa gets a waiver.
For what it is worth Mballa has a number on the roster, which Johnson did not have last year.
