Arizona Cardinals offensive lineman Jonathan Cooper was a holdout on the first day of proper training camp Friday due to a contract dispute. With the rookie wage scale in place, Cooper isn't arguing over the value of his contract, meaning the only sticking point is offset language. Given the unlikelihood of Cooper actually getting released prior to the end of his rookie deal, it all seems a bit silly but agents have very little to negotiate at this point and want to get the best deal they can for their clients.
Here's what else you might have missed from Friday:
Carolina Panthers linebacker Jon Beason restructured his contract on Friday, taking a significant paycut for the 2013 season. Beason fill earn a fully guaranteed $1 million this season, which is a reduction of $4.25 million from his original base pay for the season. Beason has dealt with multiple injuries over the past few seasons and has a lot to prove this year, especially given that Luke Kuechly replaced him so well last season.
Minnesota Vikings running back Adrian Peterson is in favor of the NFL testing for HGH. Peterson says that there are people in the NFL using HGH and he believes they should be discovered and punished for their use. Peterson of course maintains that he himself is clean. The league appears to be getting closer to HGH testing, with the NFL and NFL Players Association agreeing to a study to determine what levels of HGH should be considered "normal" for players in the league.
Kansas City Chiefs offensive tackle Eric Fisher has signed his rookie contract. He's one of the final first-round picks to sign a deal, and it's significant given that he was the No. 1 overall pick in the draft. Rookie contracts are much simpler thanks to the wage scale, but as noted above with the Cooper news, there can still be hangups.
Some court documents were unsealed in the Aaron Hernandez case, and among those documents are photos taken from Hernandez's home security system. Multiple photos seem to show Hernandez holding a handgun of some sort. At this point, this is all alleged, given the poor quality of the photos, though it is suspected that state prosecutors have better images.
