The Vikings are exercising their fifth-year option on linebacker Anthony Barr, a source tells Tom Pelissero of USA Today (on Twitter). The move was expected, but we did not have confirmation of it until today. 
In 2016, Barr started in every regular season game for the Vikings and totaled 70 tackles, two sacks, four passes defensed, and one fumble recovery. For the second straight season, he earned a Pro Bowl nomination for his work.
Interestingly, the advanced metrics at Pro Football Focus gave Barr a dreadful 43.1 overall score, despite him earning the fifth-highest pass rush mark of any qualified linebacker. This comes after being ranked in the top 30 amongst qualified linebackers as a rookie and earning a stellar 91.7 score in 2015.
Barr is now scheduled to earn $12.306MM is 2018, as shown in PFR’s Fifth-Year Option Tracker for 2014 first round picks.
