I don't have any "insider" information on the person Riley might hire as his DC. My guess is that there are very few people inside the OU program that might even have a clue. I think Riley is keeping this hire really close.
What I do think is that all of what we have learned since Pete Golding name surfaced is that the current situation points toward him being the choice. The fact that all the noise of the pending OU DC hire has gone away. No one knows anything. If, Riley had interviewed other prospects the word would have gotten out. We haven't heard a word about other prospects for the job.
I think the lack of news or rumors points to Pete Golding. If, it is Golding, I seriously doubt we will know until the last whistle blows in the final game of the playoffs.
