Brian Robison Signs 4-Year, $28 Million Extension with Minnesota Vikings

The Minnesota Vikings have locked up one of the league's top pass-rushers, and it wasn't Jared Allen. On Wednesday, coach Leslie Frazier announced the team had agreed to a contract extension with Brian Robison.

The team's official Twitter account also shared a photo of Robison inking the dotted line:

Later in the day, ESPN's Adam Caplan reported that Robison's deal will be worth $28 million with $13 million guaranteed:

That's a nice chunk of change for the Vikings, but recent history says Robison is worth it. The 30-year-old might not have the star power of Allen, his fellow defensive end, but he's very productive in his own right. Robison's been with the team since 2007, but really elevated his game since becoming a full-time starter in 2011.

Pete Damilatis of Pro Football Focus offered some perspective of Robison's ability to rush the quarterback:

As such, Frazier said he's looking forward to keeping Robison around through 2016:

Like Robison, Jared Allen entered 2013 in the final year of his contract. Allen is still among the league's elite pass-rushers and will demand a big payday for his new deal, leading to speculation about his future with the club, like from ESPN's Kevin Seifert:

NationalFootballPost.com's Joel Corry meanwhile, thinks this might be the final year to see Allen in a Vikings uniform:

Allen is currently making more than $17 million, according to Spotrac.com, and has done nothing to diminish his value this year with 3.5 sacks in four games. While he might not receive Mario Williams money (6 years, $100 million), Allen will surely be an expensive player for the Vikings to consider keeping around. With the emergence of Robison, it might be time to find a cheaper—albeit less productive—player than Allen.
