Mayo, as much as any player in recent memory, appears to be the very sort who would invite this kind of attention. His very interest in USC is said to be based on its locatin in a media market where he can begin to cultivate endorsement deals. Mayo has no ties to USC that might make him stop and think about the consequences of his actions on the program after he is gone and anything he does that violates NCAA rules would likely not become an issue until after his one year is over.
It was clear before the NCAA rule change that he intended to go straight to the NBA and it is not unreasonable to conjecture that he is consciously looking for ways to exploit the NCAA to his advantage.
And this is a case where I would have trouble trashing the kid if he does break the rules. It is not like he has gone begging for the attention he is getting and his motivation is certainly not a mystery. The huge amounts of money changing hands is the dark side of NCAA sports and I might even get a chuckle out of watching a kid like this turn that to his own advantage.
There is no 'student' in this student-athlete. He wants dollars and there are zero consequences to him for any action he might take while at USC. Zero incentive to follow the rules other than not getting caught before his year is over so he can continue to use the major networks to showcase his talent.
Further, agents know this and will do anything they can to win the Mayo lottery.
IMO this would be a very risky pickup for the Trojans and they would have no one to blame but themselves if he takes them down. Did they learn nothing from Reggie Bush? What does Mayo have to lose? What do the agents have to lose? Only USC can lose from this one.
