The Vikings had the second-best receiver in the NFL last season, in terms of yards per route run, in Stefon Diggs. It was his best year in that regard, but he’d been top 20 more or less for the past few years before that too. They also had him under contract at $12 million/year which, in light of Amari Cooper’s $20 million/year deal signed recently with the Cowboys, looks to be a bargain contract - with four years left on it.
Diggs was a 5th round draft pick for the Vikings back in 2015.
