Morris Claiborne got on Terrance Williams' nerves the minute the competition started at training camp for the Dallas Cowboys.
The third-year cornerback pulled and grabbed the receiver aggressively enough to prompt a heated, facemask-to-facemask exchange that ended with a shove.
Claiborne had already told reporters he was ready to prove he was worthy of Dallas' dramatic move up the draft board to get him with the sixth overall pick in 2012. He didn't waste any time showing some urgency.
Claiborne says he's "not accepting anything less than great" from himself after just one interception in each of his two years.
