With Denver's ground game churning up a league-best 208 yards a game behind Tebow -- the Broncos averaged just 101.8 yards rushing with Orton under center -- teams are stacking the box to slow down the quirky quarterback running the college-style read option and his trusty tailback, Willis McGahee.
That's left Eric Decker in single coverage and he's shown a knack for beating his man downfield for big gains and clutch catches that have been a major ingredient in Denver's 5-1 run since Tebow took over.
"He does have some deceptive speed, and he runs good routes, as well," said Minnesota coach Leslie Frazier, whose Vikings (2-9) host the Broncos (6-5) on Sunday. "But part of it is they're running the ball so effectively -- the No. 1 rushing team in the league -- that you commit so many people to the run and all of a sudden Eric is behind your secondary.
"Then you're kicking yourself, but you feel like you have to stop the run. Sometimes you're trying to do it with 10 or 11 people, and there he is behind your secondary."
