Adrian Peterson was noticeably absent from the Minnesota Vikings' organized team activities this week, and the reinstated running back said that it had nothing to do with him asking for a trade from the team. He later uploaded a series of tweets that explained his frustration with the "one-sided" nature of the NFL contracts that Peterson believes doesn't favor the players. 

Vikings coach Mike Zimmer was blunt about Peterson's stance and said that he has "really got two choices. He can either play for us or he can not play."
