Superman's alter ego
Philadelphia, PA (Sports Network) - While all his biographies claim he is from Palestine, TX, I believe there is now enough evidence to go public with the truth -- that Minnesota Vikings running back Adrian Peterson is the son of Jor-El and born on the planet Krypton.

How else do you explain his other-worldly performance this season?

When Peterson was injured in a game against Washington last December, he was diagnosed with ACL, MCL and meniscus injuries and underwent reconstructive surgery on his injured left knee two days before the New Year.

For most mere mortals, the recovery time for an injury like that is 12-18 months. Even then it usually takes another year before the player returns to pre-injury performance levels ... if ever.

As an example, I give you another great running back -- Terrell Davis. He rushed for 2,008 yards and 21 touchdowns in 1998-99 and was the best player in the NFL winning the AP Offensive Player of the Year Award. He also led all players that season with 361 fantasy points.

The following season he had ACL and MCL surgery after injuring himself making a tackle in the fourth game of the season against the Jets. "TD" returned to the field 11 months later, but was never the same, rushing for just 282 yards in 2000 and 701 yards in 2001. He retired from football after the 2001 season.

Peterson had surgery just before New Year's Day but was running by the end of February. In May, barely five months after major knee surgery, we were already hearing reports that seemed incredible.

Teammate Percy Harvin, a burner who in high school back in Virginia won gold medals in the long jump, triple jump, 100-meters and 200-meters, reported that Peterson twice beat him in sprints up a steep hill.

Harvin wasn't the only one thinking something extraordinary was happening here. Quarterback Christian Ponder had similar thoughts.

"The guy, number one, is a freak athlete, and for him to be doing the things that he's been doing so early after surgery is unbelievable," said Ponder in June.

Most experts predicted that Peterson had a chance to be in uniform on Opening Day 2012, but that he certainly wouldn't be playing at his old level. Not at the start of the season and probably not until the following season. They expected Peterson to share the rushing attempts with Toby Gerhart at the start and slowly assume the majority of the workload as the year progressed.

Peterson had other thoughts, however.

In the opener against Jacksonville, just nine months removed from reconstructive knee surgery, Peterson carried the ball 17 times for 84 yards and two touchdowns worth 20 fantasy points. He hasn't stopped running.

"All-Day" revealed that he hurt his ankle on his first carry of a 17-carry, 88-yard effort in Week 5 against the Titans.

Major knee surgery couldn't stop him and the sprained ankle didn't either. In fact, Peterson has gotten better not worse.

In Week 6, he totaled 129 yards from scrimmage.

Starting in Week 7 against Arizona, Peterson has been simply spectacular. He burned Arizona for 153 yards, Tampa Bay for 123 yards, Seattle for 182 yards and last weekend, while also fighting the flu, he was out of this world, rushing for 171 yards against Detroit.

Heading into his team's bye, Peterson leads the NFL in rushing with 1,128 yards, is first in rushing yards per game (112.5), tied for second with seven rushing touchdowns and third in yards per attempt (5.8). He's also leading all fantasy running backs with 192 points.

"He's amazing," said Harvin. "I told him the other day I don't think he's human."

Harvin might be right.
