If there has been one running theme in all the Vikings games I've seen is that Keenum stays clean most of the game and has a rocking chair to sit in and pick out his receivers.
Keenum has not been prone to throwing the picks because of this also.
Vikings have a good running game too.
All that being said, the Rams are just as good and I think what beat the Rams in Minnesota the first time was a matter of strategy on the part of Sean McVay.
We shall see if they play again if the Rams and McVay adjust their game plan.
