It would be a HUGE indicator if true. That's a dead give away if true. For now it could just be the rumor mill doing what rumor mills do.
From what I know from the articles I have read it sounds like their home is Iowa. That's huge to many people as family and friends is the most important thing to a lot of people. Would a coach give up family, friends, and home a few more dollars in their pocket. Yes, those people do exist but hopefully some people value more that a few dollars more.......... even a few hundred thousand dollars more.
Remember the quote from Lickliter's own young son when they were all discussing it as a family. His son was quoted as saying....... "but Dad it's Iowa!" Probably now he says "Eff Iowa!!!" I am sure it never really was home for Lick's family.
