Last Saturday, against the Washington Redskins, fans watched in horror as Minnesota Vikings running back Adrian Peterson’s knee broke the laws of anatomy. Unfortunately for Peterson and the Vikings, the consequences might be costlier than just missing the last game of the 2011 season.

After undergoing an MRI, it was revealed that Peterson had torn both the ACL and MCL in his left knee, among other damage.

Peterson underwent surgery on Friday to repair the torn ligaments and the procedure was a success.

“We’ve received word that Adrian underwent successful knee surgery with Dr. James Andrews and is now resting comfortable,” the Vikings announced Friday afternoon. “Adrian is in our thoughts, we wish him a speedy recovery and we look forward to seeing him when he returns to Minnesota.”

Typically, this type of injury would take anywhere from eight to nine months to heal before the knee could begin to undergo any sort of physical exertion. The Vikings, however, have already made it clear that they expect Peterson back and ready to go to kick off the 2012 regular season in September.

Despite all of the optimism radiating from the Vikings’ front office and staff, I still have my doubts that Peterson is going to return as the same running back that carved up NFL defenses for the past five seasons.

Don’t get me wrong; I’d love nothing more than to have Peterson suited up and ready to wreak havoc at the beginning of the 2012 NFL season. He’s the centerpiece of the Vikings’ offense and the prime building block for the future of this franchise. But to be so optimistic about an injury that could hinder Peterson for the rest of his life seems a bit naïve.

To illustrate my point, I call your attention to the Daunte Culpepper fallout of 2005.

Arguably the last quality quarterback the Vikings could call their own, Culpepper was on the verge of carving his own niche in the NFL. He was coming off of a 2004 season that saw him throw for 4,717 yards while setting the since-broken NFL record for total yards in a single-season by a quarterback with 5,123. The Vikings’ former first-round pick was a three-time Pro Bowler in his first six years in the NFL. For Culpepper, everything was falling into place until one fateful day in 2005 against the Carolina Panthers.

During a Vikings’ mid-season matchup with the Panthers, Culpepper had his knee taken out, tearing his ACL, MCL and PCL in the process. I won’t bore you with any numbers, but it’s safe to say that Culpepper was never the same player after rehabbing from the devastating injury. He spent a few more years jumping from team to team in the NFL before finally settling for the UFL, where he still struggles to dominate against much weaker opposition. Prior to the start of the 2011 NFL season, Culpepper made himself available to quarterback-needy NFL teams, and not a single team bit.

Although many will argue that Peterson will be fine considering that he didn’t pull off the tear trifecta a la Culpepper and he’s a different breed of athlete, a knee is a knee. Regardless of the person or their will to persevere, a knee simply isn’t supposed to bend that way and damage like that is usually a life-long limitation.

A big reason as to why Peterson is so great is his ability to cut on a dime and burst through the hole with overwhelming strength. That relentless power and explosiveness that he runs with makes him so dangerous. However, with a knee injury of this magnitude, that explosiveness and burst are gone. No stable knee equals no bowling over defenders with ease. Without strong, healthy knee ligaments, Peterson can’t cut properly and the Vikings’ homerun threat is degraded to a one-dimensional back who is better off watching from the sidelines.

The biggest factor at this point will be how Peterson’s knee responds to the rehabilitation and whether or not the Vikings wait until he’s as ready as can be. The worst thing Peterson could do is play prematurely and cause even more damage to the knee. Especially at a wear-and-tear heavy position like running back, Peterson’s at horrible risk of causing irreparable damage if he plays before the knee is 100 percent healthy.

The Vikings will play Peterson when they feel he is ready, and he’s a smart enough player to not insert himself into the lineup before his knee is properly prepared to take a beating. The main concern, though, is whether or not we’ll ever see the lethal version of No. 28 again.

If there’s any player who can bounce back from an injury of this magnitude and still play at the same level, it’s Peterson. He’s as elite of an athlete as they come, and he’ll be working non-stop offseason to get himself primed for football. Add in the training prowess of Vikings head trainer Eric Sugarman and you’ve got a recipe for success. I reiterate, though: there’s a reason knees don’t bend sideways.

I’m not rooting for him to fail; I’m just trying to prepare you for the reality that All Day may never again play like the All Day so many Vikings fans have come to know and love.

Could this be the beginning of the Toby Gerhart era in Minnesota? Only time will tell.

Dec 31, 2011 – Minnesota Vikings cornerback Benny Sapp was cited for misdemeanor assault on Friday after an altercation with security at Children’s Memorial Hospital in Minneapolis.

Reportedly, Sapp was trying to drop off his son with his wife who was visiting at patient at the hospital but security officers weren’t ready to allow Sapp to skirt security regulations to park near the hospital entrance for the quick exchange. Minneapolis police were eventually called in to clean up the mess.

“Mr. Sapp pushed one of the security officers and drove his vehicle toward the exit of the ramp, where there was another confrontation with a security officer standing in front of the vehicle,” Palmer said.

Sapp “chest-bumped” the officer before getting back into his vehicle and trying to drive past the officer, Palmer said, adding “there was no indication the vehicle touched the security officer.”

Sapp has been playing through a shoulder injury for the Vikings but this incident may impact his availability for Sunday’s season-ending game against the Chicago Bears.

Downtown Minneapolis stadium rendering

MINNEAPOLIS — Minnesota Vikings officials insist their first choice for a stadium remains the St. Paul suburb of Arden Hills.

But they are also taking a closer look at a site in downtown Minneapolis near the Basilica of St. Mary.

The Star Tribune reports (http://bit.ly/tVHgS0 ) the team is conducting a traffic analysis of the site because the property’s ability to house a stadium was relatively unknown. The $1.03 billion proposal is the least known of the team’s possible new homes.

Lester Bagley is the team’s vice president for stadium development and public affairs. He says the team does not yet have a preferred stadium site in Minneapolis.

The stadium’s location is one of the project’s biggest unsolved hurdles along with how to publicly fund its construction.
