The Minnesota Vikings have a pretty good passing game: through 14 weeks, the Vikings rank in the top 10 in both ANY/A and passer rating. What makes it really weird is that the top two members of the passing game — the quarterback and leading receiver — were both undrafted free agents. Case Keenum went undrafted in 2012 after a stellar career at the University of Houston. The Vikings leading receiver is Adam Thielen, who went undrafted in 2013 out of Minnesota State–Mankato. Together, they are the driving force behind the 2017 Vikings efficient passing attack.

The Vikings will become just the 7th team since 1970 with their top passer and top receiver both having gone undrafted.

• The 2014 Browns had Brian Hoyer and Andrew Hawkins, although unlike the Vikings, this team wasn’t very good. Cleveland went 7-9 (which is of course, very good for Cleveland) and ranked 23rd in ANY/A.

• The 2009 and 2010 Cowboys make the list, too, thanks to Miles Austin and a pair of quarterbacks. In 2009, Tony Romo and the Cowboys ranked 4th in ANY/A and went 11-5; the next year, with Romo hurt, Jon Kitna led Dallas in passing but the team went 6-10 and ranked 12th in ANY/A.

• In 2004, the Titans passing attack was led by Billy Volek and Drew Bennett. For a short run, the combination was outstanding, but overall, the Titans finished 19th in ANY/A and 5-11.

• In 2000, Jay Fiedler and Orande Gadsen were the key components in a mediocre Miami passing attack. Those Dolphins teams were defined by their defense, and the Dolphins went 11-5 despite ranking 19th in ANY/A.

• In 1992, Dave Krieg joined the Chiefs as a 34-year-old veteran. He was undrafted, as was Willie Davis, who had zero NFL catches to his name prior to the season. Davis wound up leading the Chiefs in receiving, and together, Krieg and Davis helped the Chiefs rank 8th in ANY/A and finish 10-6.

The table below shows all teams since 1970 where neither the quarterback nor the leading receiver (in receiving yards) were drafted within the first 200 picks. It is sorted by ANY/A rank that season:

There are, unsurprisingly, a few combinations that show up multiple times on the list. Warren Moon and Drew Hill were the key parts of the Oilers passing game for five straight years in the back half of the ’80s. Wade Wilson and Anthony Carter made the list for their work with the Vikings in ’87, ’88, and ’89. Steve DeBerg and Stephone Paige did it with the Chiefs from ’88 to ’90. Ryan Fitzpatrick and Steve Johnson led the Bills in passing and receiving, respectively, in 2010, 2011, and 2012. And Brian Sipe and Reggie Rucker led the Browns in ’76, ’77, and ’78.
