I watched the video. And I (being totally honest here) despise Jay.
Jay is a good public speaker. I am not bothered by Jay defending his father.
Jay is also, IMO --- entitled, non-self-aware, and unable to admit the true reason he isn't currently coaching football (hint: it's not the Freeh Report). Is what it is. For reasons discussed many times here, I find his lawsuit against Penn State absurd.
If he'd go be an OC or a QB coach at some FCS school --- jobs that he could undoubtedly get if he didn't think they were "beneath" him --- I'd root for him. Honestly, I would. That would require Jay to stop playing the "victim" card and start taking some personal responsibility for re-building his coaching career.
I don't think Jay has the personal fortitude within him to do the latter, however.
