Give me one reason for a coach not to say "I'm staying at XXX"...if that is what he plans to do.
And spare me the "KF doesn't do that" spiel.
IMO, there is only one reason a coach keeps quiet when being seriously rumored for other jobs - he's fishing for a deal - either with that school or another.
Maybe KF in fact does not want to go to Michigan. However, there are a number of other jobs that are open and may come open before this thing is over. Him being mentioned along side the Michigan job is a nifty marketing item.
The guy may very well stay at Iowa, but his silence on the issue is saying a lot right now.
