Blackmon had a fine 2015 campaign for the Redskins. The 31-year-old appeared in 15 games with 10 starts, registering 49 combined tackles, three forced fumbles, two interceptions and a sack.
Mike Garafolo of Fox Sports noted how Washington had minimal expectations for Blackmon when it brought him aboard prior to last season:
Washington general manager Scot McCloughan did a fine job retooling the Redskins roster for what was eventually an NFC East division title this past year. Blackmon turned out to be a diamond in the rough who helped Washington's secondary in a big way.
Although the Redskins finished 28th in total yards allowed, they were 17th in scoring defense and played well enough down the stretch to help Washington win five of its last six games.
The Redskins released free safety Dashon Goldson last week. Goldson racked up 110 combined tackles in 2015 but also garnered the unsavory distinction as Pro Football Focus' worst-graded safety of the year.
McCloughan and Co. still have some work to do to shore up Washington's defensive backfield. Re-signing Blackmon is a nice first step in that process, though.
