If money was the only factor, do you think if Joe C. had offered him whatever he ended up taking, from Day 1, LK would have come straight to OU? I don't. That is why I say money wasn't the biggest factor.
Basically Joe C. needed to wear him down. Needed to keep LK thinking about it for days, or weeks. Yes, increasing the money was a factor in that, but if you think LK is somehow living his life differently now, then he would have with $500k less, or a $1M less per year, you are crazy. That money shouldn't mean anything to LK. He has been around long enough, and earned enough, that he could retire comfortably today, never earning another penny. I get what you guys are saying, I just don't think it was a money only issue. But that was Joe C.'s best/only way of keeping the conversation going, to keeping LK on the hook, so to speak.
Unfortunately, we'll never know how it would have played out. I know BOB wanted LK after Sampson, but I don't recall many other posters wanting him, nor was his name in the media. I still don't think he would have taken the job then, but that is jmo.
