. I'll goes as far to say the said meeting was a informal chat when miles was in Fayetteville, most likely on the field.
I'll concede that Long and Les met in person or talked on the phone, they've known each other for a while and go back to both having spent time at Michigan.
It could be as simple as Long asking about another coach and talking to Les for a personal reference.
But that would be too simple since it would be exactly what Les said it was and Les isn't an honest trustworthy individual.
