I call BS on Hurley when he says him and UCONN already ironed out the number. I got a feeling that number changed slightly on the return flight from LA.
I also do believe there was a number he would not walk away from - and maybe 15M per year was it. But this is smart of him to say - because he has been open and said in interviews, he one day would consider the NBA as a coach. And by saying there was a number he wouldn't walk away from - that leaves the door open and keeps other teams calling him in the future.
As opposed to Coach K - when he interviewed with the Lakers and turned them down, I think the entire NBA reacted with - he is staying in college, don't waste your time. This at least keeps Hurley on the list of jobs for the NBA - which might be the Lakers again in 3-4 years.
