I'll go by PW's own words that were quoted in the PD yesterday.
If he was not interested, would he have said so when given the opportunity? I think it was footballscoop that reported, look for PW to be announced Dec 19th. I think the whole time, U of A has just been waiting for PW to get done with his task at hand. The rest of the floated rumors are just that. How does footballscoop get there info? Think about it. One of the funnier things I read on there was, no word on the HC job for PSU, I know they haven't done this in a long time, but you need to contact us.
