So, back in 2008 these SWATS guys gave out the chips, stickers, whatever to the uat players with an agreement that after they graduated/left the University they'd endorse their product? Hmmm, this sounds similar to the Reggie Bush case and the Shapiro case.
Give something of value to player(s) and/or family member(s) with an agreement that the player(s) would give back to said person (agent, monetary, endorsement, etc.).
Player(s) renegs on the deal a couple years later.
