which team can keep their QB clean/get pressure?

That's a big factor in this game to me. The Vikings have a very good pass protecting OL. Regardless of if Keenum is prone to mistakes or not if he's kept clean he can do well, especially with the WRs he has.

Same with the Rams. They need to keep Griffin and co. at bay. I don't see Gurley having a big game on the ground but maybe if they stretch runs outside and away from Joseph he can get some yards. This might be a game where he has more receiving than rushing yards.
