Right now, the math isn't pretty.
Add Case Keenum and the Steelers defense, subtract the Saints defense and Sam Bradford and Vikings receivers produced:
- Two catches for 27 yards by Stefon Diggs with Keenum vs. seven catches for 93 yards and two touchdowns with Bradford
- Four catches for 45 yards by Kyle Rudolph with Keenum vs. three catches for 26 yards and a touchdown with Bradford
- Five catches for 44 yards by Adam Thielen with Keenum vs. nine catches for 157 yards with Bradford
- No receiver with more than five receptions or 45 yards
- 237 yards of total offense with Keenum; 470 yards of total offense with Bradford
Long story short: Vikings receivers looked and were better with Bradford than Keenum.
It's hard to imagine the Vikings offense maintaining the pace it set in Week 1 – can't play the Saints every week – but Week 2 was quite the step back.
But it's likely the worst-case scenario.
Take last season, for example.
In nine games Keenum started for the Rams:
- In PPR, 18 times a receiver posted 10-plus points (2.0 receivers per game on average) and seven times a receiver posted 15-plus points (.77 per game)
- In standard scoring leagues, seven times a receiver posted 10-plus points (.77) but only once did a receiver post 15-plus points (.11 receivers)
- He threw for 250-plus yards passing four times, 300-plus yards once and three-plus passing touchdowns once
Compare that to Vikings quarterbacks in 16 games in 2016:
