Pittsburgh limited Adrian Peterson to 21 yards in 12 carries for a 1.8 average Saturday night in a 12-10 victory.
In two preseason games, Peterson has rushed 20 times for just 51 yards. The offensive rookie of the year last season, Peterson gained an NFC-best 1,341 yards on 238 carries (5.6 yards per carry).
Last year he gained 146 yards in 30 attempts (4.9 yard-average) in the preseason.
Despite Peterson's slow start, Mike Tomlin, the former Vikings defensive coordinator and now the head coach of the Steelers, looks for the former Oklahoma star to break out.
"I'm sure that's not anything that's new to him," Tomlin said of Peterson facing stacked lines. "I'm sure he saw quite a few eight-, nine-man fronts in Oklahoma and in high school and in every level of competition he's been in. He sees it because he's a special player, he's a special runner. He's found ways to be successful in the past, I'm sure he'll find ways to be successful in the future."
Tomlin was impressed by many of the players he coached the one year he was with the Vikings.
"I thought they were a physical football team," Tomlin said. "They're strong in the lines of scrimmage. They play the battle of attrition. They're always going to be a rough-and-tumble outfit, I know that's Brad's [Childress] personality. I have a great deal of respect for them."
Tomlin had good things to say about two former Gophers now with the Steelers -- running back Gary Russell and tight end Matt Spaeth.
