Vikings-Rams pregame thoughts: Which team's pass rush will have the biggest impact?

Here's what I'll be watching during the Vikings' game against the Rams at U.S. Bank Stadium today:

To get away from quarterback talk for once, what I'll be watching early in the Vikings-Rams game are the pass rushes.

The Vikings rank first in the NFL in sacks and get to face a Rams team missing star tackle Andrew Whitworth.

The Rams rank fifth in the NFL in sacks and get to face a Vikings team that got manhandled by the Bears' defensive tackles on Monday night.

Matthew Stafford and Kirk Cousins are both good at putting up big numbers, and neither is the kind of quarterback who routinely overcomes difficult situations.

So will Aaron Donald ruin the Vikings' offensive game plan?

Or will someone like Michael Pierce of D.J. Wonnum wreck the Rams'?

Pierce is an excellent player who can push the pocket back on a quarterback. Wonnum has been the Vikings' most-improved player. And the expertise of Andre Patterson and Mike Zimmer has shined in this aspect of the game.
