Minnesota Vikings' Adrian Peterson may have just proven that he is still the best running back in the NFL when he delivered an impressive performance against the Detroit Lions in week two.

The Vikings triumphed over the Lions this Sunday, but what caught the attention of football fans and other players is that Peterson's skills are still there. The 30-year-old running back delivered only 31 yards on 10 carries in Minnesota's first game against the San Francisco 49ers, but he came back with a total of 192 yards against the Detroit team, NFL.com reported. Peterson rushed 134 yards of it through 29 carries, noted an article from Bleacher Report.

His amazing play on the field was enough to make the 2012 NFL Most Valuable Player still mark his spot as the top RB in the league, in the eyes of San Diego Chargers end Corey Liuget, San Diego Union-Tribute informed.

"He showed on Sunday he's still a No. 1 elite running back in the NFL," Liuget said.

Peterson, the rookie RB who reportedly demolished Chargers' defense in 2007, still has what it takes to bring it down again in week three, if the Chargers will not execute a great strategy to stop him, says Eric Weddle. Weddle, who was a Chargers rookie safety way back in 2007, personally witnessed Peterson's power, The Orange County Register noted. Peterson reportedly posted an NFL single-game rushing record with 296 yards via 30 carries and three touchdowns on that fateful day of Nov. 4 eight years ago.

"One guy's not going to bring him down. You've got to play the (defensive) rules, play your gaps, do what you're coached to do -- and gang-tackle him. That's the recipe. Don't rely on just one guy. Everybody runs to the ball and does what they're supposed to do," Weddle said.

Weddle also observed that even though Peterson was off the field for almost a year, due to reported legal issues, the Vikings' RB is far from rusty.

"He looks fresh, explosive, physical. He may not have the breakaway long speed that he used to have...But jeez, he bolts through that hole and looks as good as ever," Weddle said.

If the Chargers will not be careful with their defense, they could repeat history.

Aside from impressing other players, the Texas-born athlete also impressed his coach Mike Zimmer.

"I did love the way he ran. He ran extremely strong, he had great feet in and out of the hole, he had excellent vision, and he ran with a lot of physicality," Zimmer told SiriusXM NFL Radio.
