They are not "set" on anything lol. That's the whole point. No decisions have been made.
At least Dave seems to get it. Decoucey might be reputable, but he doesn't follow the team. He doesn't have any sources in the SJU administration or with any boosters.
Who he does have a relationship with is Lavin's agent who represents a number of coaches in the business. So where do you think his information is coming from?
Thats not to say this is something sinister ... it's not.
Its just how the game is played. Lavins agent is trying to get him some press and push the debate towards an extension.
