The fact that Vikings superstar running back Adrian Peterson has scored only two touchdowns this season is surely one of the major reasons that the Vikings are having trouble producing in the red zone.
The Vikings offense has gone quite a while without Peterson scoring, a rarity over his great career.
He hasn't recorded a touchdown since reaching the end zone twice in Week 1 against Jacksonville, going five weeks without a score. That is the longest touchdown drought of his career.
Prior to this season, the 2007 first-round draft pick hadn't gone more than three weeks in a row without scoring, and that only happened once, in Weeks 14-16 of the 2008 season, although he still rushed 72 times for 346 yards in those three games: victories at Detroit and Arizona followed by a home loss to Atlanta.
Four other times, Peterson went back-to-back games without a score: once in his rookie season of 2007, twice in 2008 and once in 2010. In the 12 games he played last season, he scored a touchdown in all but three of them, finishing with 13 touchdowns (12 rushing, one receiving). Right now, he's on pace to score only five touchdowns.
Surely the Vikings know that getting Peterson into the end zone and giving him the ball when they get inside the 20 will help turn around their current struggles.
The Vikings rank 19th in the NFL in red zone touchdown scoring percentage at only 50 percent. That percentage was greatly affected by them scoring just two touchdowns in seven red zone attempts against Washington last week. Their percentage this year is even down from last year's miserable 3-13 season, when they scored touchdowns on 56.6 percent of their chances.
Still the Vikings have been successful in at least producing points once they reach the red zone -- they have made 22 trips inside the 20 this season and have scored 11 touchdowns and kicked 10 field goals, a 95 percent success rate. The only time they haven't scored is when Christian Ponder threw an interception with 22 seconds left in the game Sunday.
