One of the first players to cash in when NFL free agency began Thursday was offensive lineman , who signed a four-year deal with the Los Angeles .If Okung wants to thank his agent for a job well done on the multimillion-dollar deal, all he has to do is look in the mirror. Thats right: Okung served as his Kyle Fuller Jersey own agent during negotiations and, apparently, hes pretty good.The offensive lineman was able to talk the Chargers into a four-year, $53 million deal that that included $25 million in guaranteed money, according . Although Okung was chastised last year for making a long-term deal with the that was in reality a one-year commitment, this one appears to be the real thing.In 2016, the offensive lineman, who was again serving as his own agent, agreed . However, Okung didnt see most of Cody Whitehair Jersey that money. After making $8 million for the 2016 season, the Broncos decided not to pick up his option for 2017, which made him a free agent. This time around, Okung made sure to score a contract that included more guaranteed money. Plus, since he doesnt have to pay a fee to his agent, Okung is going to be taking home more money than anyone else who might sign a similar deal.Of course, there is a downside to being your own agent: You have to know all the rules.According to Mike Klis of 9news.com in Denver, Okung Mike Singletary Jersey (and the Chargers) may have broken NFL rules during their negotiations. Although there is a legal tampering period where teams are allowed to talk to agents in the 48 hours before free agency begins, that rule doesnt apply to players who are serving as their own agent, because teams arent allowed to contact during the tampering period.Basically Okung wasnt allowed to talk to any teams before 4 p.m. ET on Thursday. According to Klis, his NFL sources believe that the Chargers violated that rule Charles Leno Jersey . Industry sources believe Chargers may have tampered with Ru sel Okung who was not supposed to negotiate till 2pm Thursday.

Well, not off the field. Based on Okungs play from 2016, they might start to worry about whether he can protect . Chargers signed Ru sell Okung. He allowed 57 pre sures last year.
