From a study standpoint, it has been a unique week for Vikings defensive coordinator Alan Williams and his players as they prepare to head to Houston with hopes of defusing one of the league's most potent offenses.
It's not that the Texans do anything complex. But what they have assembled is a steady, balanced, minimal-error attack that can steadily suck the life out of an opponent.
That was obvious again last week as the Texans clinched the AFC South with a methodical 417-yard output in their 29-17 victory over Indianapolis.
First, it was Andre Johnson.
On the opening snap, the All-Pro receiver took a quick-hit pass from Matt Schaub and ate up 9 yards. On second down, with a play-action fake, Schaub again looked to Johnson, deep down the middle for an all-too-easy 52-yard gain.
Just like that, the Texans were in position for their first score, a 29-yard field goal by Shayne Graham that gave them the lead for good.
On Houston's following drive, Johnson capped a 13-play, 57-yard march with a 3-yard touchdown, continuing a day during which he caught 11 passes for 151 yards.
And then it was Arian Foster. Over and over again.
