Someone told a non-panther front office person- " Mickey and Payton LOVE Marshall and are targeting him with their 2nd round pick". That person believes it and calls a panther personal and tells them the news. Can happened with agents, "Saints guaranteed me Marshall will be the 60th pick ". Ten years of build up trust and relationship can go be invaluable. Now it works both ways, that panthers person must give information that their team could value.
Saints person *could be a source, I mean 5k-10k could buy a few rumors with some proof. Tho its faaar more likely the story above with a agent/former employee.
