The reports this week that Johnny Manziel was paid by autograph brokers to sign items for later sale might merely be the tip of a very large NCAA eligibility-threatening iceberg as the collection of one EBay memorabilia salesman makes clear.

As first documented by Busted Coverage highly rated EBay user "the_hub_collectibles" has 19 verified items for sale autographed by Manziel. But he also has 19 items available signed by South Carolina Heisman candidate Jadeveon Clowney and 11 signed by Louisville quarterback Teddy Bridgewater. There's also a handful signed by Ohio State quarterback Braxton Miller.

Texas A&M blog Good Bull Hunting also documented a second eBay user with a large number of Clowney items both sold and for sale.

A South Carolina official told's Bruce Feldman regarding the memorabilia that "our compliance folks are aware of it. We haven't had an indication that there's been a violation."

The State reported Wednesday that Gamecock compliance has looked into multiple instances of Clowney memorabilia appearing on eBay -- including a photo of Clowney signing items in a hotel room in what might now be an unfortunate echo of the ESPN Manziel reports. But associate athletics director Chris Rogers told the paper that they have yet to find any violations.

"We have investigated things that have been on EBay with him and student-athletes before" Rogers said. "In the situations I can say we looked into there was no further for us to go and we determined there was no violation ... [B]asically what we are trying to ascertain is 'Is there credible enough information for us to investigate further?'

"If you look up Jadeveon Clowney there are hundreds and hundreds of hits. We are trying to ascertain which of those are worth pursuing and which are not."

Steve Spurrier himself reportedly said on ESPN that he wasn't aware of Clowney ever accepting compensation for his autograph.
