No disputing value of Jared Allen trade

EDEN PRAIRIE, Minn. — Jared Allen will return to Kansas City this weekend with the NFL's second-most sacks on the season. It's been more than three years since the Minnesota Vikings acquired him in one of the most expensive trades in recent NFL history, but it's clear that Allen hasn't fully gotten over the event.

Speaking in a conference call with members of the Kansas City media, Allen hammered former Chiefs president Carl Peterson and team owner Clark Hunt. He said Peterson "lied" to him about plans to offer him a contract extension and criticized Hunt for "choosing Carl over me."

I don't usually get too excited about this kind of cliché story line. Every now and then, it's special. But in the NFL's salary cap era, it's routine for players to change teams. If they continue playing long enough, they're bound to face their former team. Sometimes they perform well. Sometimes they don't.

In this particular case, Allen is already a high-energy player. Do we really think he'll step it up another notch because he's playing the Chiefs? After all, Peterson has long since left the team. Allen is four years removed from donning a Chiefs uniform and almost all of his former teammates have moved on as well.

What this occasion does provide, however, is a chance to recognize the extensive return the Vikings have gotten on their investment.

As you recall, the Vikings sent the Chiefs four draft picks -- including the No. 17 overall pick of the 2008 draft -- in exchange for Allen and a sixth-round pick that became center John Sullivan. Then they signed Allen to a six-year contract that paid him $25 million in 2008 and will be worth a total of $73.26 million if he's with the Vikings through its final season in 2013.

The Chiefs used two of the draft picks to select left tackle Branden Albert and running back Jamaal Charles, but I'm guessing the Vikings would pay the same price again. As the chart shows, only one NFL player -- Dallas Cowboys linebacker DeMarcus Ware -- has recorded more sacks than Allen (44.5) since the trade.

Allen didn't speak with Twin Cities reporters Wednesday. What's left to say?
