It's the off-season for the Minnesota Vikings, as well as the majority of the National Football League. But, as we know, the NFL really doesn't have much of an "off-season." There are plenty of major events to keep the wheel turning between now and the start of the 2015 season.
The following is a list of what should be all of the major events for us to keep an eye on going forward.
24 January - Senior Bowl, Mobile, AL
25 January - Pro Bowl, Glendale, AZ
31 January - NFL Honors Gala & announcement of Pro Football Hall of Fame Class of 2015 (which will hopefully include Mick Tingelhoff)
1 February - Super Bowl XLIX, Glendale, AZ
6 February - Adrian Peterson's appeal hearing, U.S. District Court, Minneapolis
10 February - First day that teams can sign player whose Canadian Football League contracts have expired (such as, I don't know, Duron Carter, maybe)
16 February - First day teams can designate Franchise or Transition Players
17 - 23 February - NFL Scouting Combine, Indianapolis, IN
2 March - Last day teams can designate Franchise or Transition Players (deadline 3 PM Central time)
7-10 March - "Legal tampering" period for NFL Free Agents. Teams can get into contact with agents of players who will be free agents, but can not execute contracts with those players until. . .
10 March - Free agency officially begins (3 PM Central time), new league year officially begins
22-25 March - NFL Annual Meetings, Phoenix, AZ
15 April - Earliest that Adrian Peterson can be reinstated by the NFL (if his appeal in February should fail)
20 April - Vikings (and other teams with returning head coaches) can start off-season workout programs
24 April - Deadline for Restricted Free Agents to sign offer sheets
30 April - 2 May - 2015 NFL Draft, Chicago, IL
8-11 May - First post-draft rookie mini-camp (will take place on either 8-10 May or 9-11 May)
15-18 May - Second post-draft rookie mini-camp (will take place on either 15-17 May or 16-18 May)
21-27 June - NFL Rookie Symposium, Aurora, OH
27 July - Minnesota Vikings open Training Camp, Mankato, MN
There are a few other camps that will take place along the way, including mandatory mini-camp for rookies and veterans, but there aren't any firm dates for those yet.
CBS Sports has a full list of events, including the "Super Regional" Combines and other events. But the list above should have the majority of the high points.
