We all know that Philadelphia sports fans can be brutal. Heck, they even jeered jolly old Saint Nick once, and are proud of it.
Their wrath can fall on anyone, at anytime. Even if you're a winner.
Case in point: Eagles QB Donovan McNabb.
When word leaked out that Andy Reid and company were willing to listen to trade offers for the five-time Pro Bowler, it signaled the end of the McNabb era in Philadelphia.
Make no mistake, the rift between quarterback and franchise is now a gaping chasm.
McNabb was placated after his benching a few years ago with a new contract and a boatload of money.
All the money in Fort Knox wouldn't appease him now.
He has an ego, just like all of us do. Finding out the team you gave your heart and soul to for 11 years is trying to dump you can cause anger and bitterness on a pretty big scale.
Reid has hinted in recent interviews that Kevin Kolb is ready to take the reins of the team and continue the success built over the past 10 years.
A statement was issued by the Eagles' media relations department that all three quarterbacks could be had for the right price.
We know that isn't true.
Kolb is going to be the guy; McNabb is in the final year of his contract and Philly has no interest in giving him a new long-term deal.
He's also due a $6.2 million roster bonus on May 5 that I doubt the Eagles are willing to pay.
Surprisingly, many Eagle diehards took to the airwaves and Internet, voicing their happiness that McNabb could soon be out of town for a second-rounder or more.
The most puzzling question in all of this is: Why are some Eagles fans so happy?
I can understand Reid's willingness to let McNabb go: If he really feels Kolb can do the job, why not go with the younger and cheaper alternative and get something for Donovan before he walks?
But the fans, that's a different story.
Some will justify their feelings by pointing out McNabb's 9-7 career playoff record and zero Super Bowl rings during his tenure, but that's just nit-picking.
Philadelphia has had its most successful decade in franchise history under McNabb. It's true that his success hasn't led to Super Bowl titles, but that doesn't mean McNabb hasn't been a great quarterback.
Look at Dan Marino, Dan Fouts, Fran Tarkenton, and Warren Moon. They didn't win Super Bowls either, but no one will deny their place among the all-time greats.
Let's take a look at some of his accomplishments:
The Eagles have made the playoffs in eight of his 10 years as a starter.
The Eagles, under McNabb, have won six NFC East titles since 2000.
The Eagles, under McNabb, have played in five NFC Championship games with one Super Bowl berth since 2001.
The Eagles have suffered only two losing seasons since 1999, the year McNabb was drafted.
When was there a time in Eagles history when they won like this?
Never. Not even back in the days of Hall of Famer Steve Van Buren.
Can Kolb be the man, with only two games of significant playing time under his belt?
That's a question that will affect this organization for years to come. It's a gamble Reid is willing to take.
If it works out, he'll be hailed a genius.
If not, the franchise could be set back for years to come.
Ralph Waldo Emerson, American philosopher and author, once said, "Be careful what you wish for, because you just might get it."
The Eagles and many of their fans will soon get what they've wished for; McNabb will be gone, and a new era will begin in Philadelphia.
And as Emerson pointed out so eloquently, sometimes getting what you want isn't a good thing.
