The Minnesota Vikings begin offseason Organized Team Activities today at Winter Park in Eden Prairie. Today is the first of three daily workouts this week. There will be seven more days of OTA’s next month, followed by a mandatory team mini-camp starting on June 18th. Vikings star running back Adrian Peterson says this offseason has been different than last season for him. Of course, last season, he was recovering from a major knee injury and this offseason he is the reigning NFL Most Valuable Player.
