I've Always Wondered About This

The NFL draft was last month and this month there have been a variety of mini-camps across the league that the drafted players take part in. But 99% of them do not have a contract. So what happens if one of them gets hurt? Well, one guy is going to find out. The Cowboys drafted lineman E.J. Whitley of Texas Tech in the seventh round. In his first camp last week, he blew out his ACL and is gone for the season. The Morning News tells me "the rookies signed injury protection waivers before mini-camp meaning the Cowboys would negotiate a contract in good faith regardless of the severity of the injury." Huh? I have no idea what that means. Some seventh rounders don't even make the team. This will be interesting.
