Greg Jennings signs with the Minnesota Vikings

The reality of professional sports, especially professional football, is that careers are inherently short and can end at any time. It's a game that takes a physical toll on participants, often rendering them disabled before their 50th birthdays. Because of that, players almost have an obligation to their families to make as much money as possible while they're playing. It's a business, and a brutal one.

On Friday, Greg Jennings made the best business decision for his family, signing with the Minnesota Vikings. ESPN's Adam Schefter passed along the news via Twitter:

Greg Jennings reached agreement with...the Vikings.

In the seven seasons since Jennings was drafted by the Packers, he's racked up 6537 receiving yards and 53 touchdowns. While his last two seasons have been plagued by injury, perhaps limiting his market in free agency, he's still remained a very effective player.

Jennings follows in the footsteps of Darren Sharper, Ryan Longwell and Brett Favre as recent Packers stars who decided to take their talents to Minnesota after the Packers decided that their demands for money or playing time had outweighed their usefulness to the team. Like those players, he will have plenty of chances to prove to the Packers that they made the wrong decision.
