Volunteering can lead to unintended Jam Ups

This comes from avid Steelers fan Big Mike regarding James Harrison's big mistake to volunteer as a long snapper - eventually losing the Steelers the game. My commentary (I disagree with Big Mike some here on how big of a Jam Up this is) is below.

How Volunteering can lead to a jam up!
After Steelers long snapper Greg Warren was carted off the field in Sunday's loss to the Giants, All Pro line back James Harrison volunteered for the job. Although having absolutely no experience at either the center or long snapper position, Harrison thought he could help his team in their time of need. With the Steelers nursing a 14-12 fourth quarter lead against the Giants, Mr. Harrison was sent out to snap the ball to punter Mitch Berger deep in their own territory. Harrison proceeded to snap the ball about 10 feet over Berger's head. Manute Bol probably could have not fielded the snap. The errant snap by Harrison gave the Giants a two point safety, a tie, the ball, and eventually the game. The next time Harrison goes up to coach Mike Tomlin and volunteers for anything other than playing linebacker, I hope Tomlin tells him to go "fuck himself".

Indeed, people get Jammed Up often by people who think they are capable of performing a task they just cannot. James Harrison thought he could help his team, he ended up helping them lose. But, in the end, it's not a true Jam Up. Harrison isn't happy about the loss. He's not happy he made a bad snap. To be a true Jam Up, there needs to be a Chauncey and a Fisher. There are many Fisher's here - the Steelers, the fans, even Harrison himself. There is no Chauncey here. Sorry Big Mike. I can't call it a Jam Up.
