Opportunity knocks for Vick
There is an old saying in the NFL that a player should never lose his starting job through injury and that he should be inserted back into the line-up as soon as he is healthy.
While that is a nice sentimental thought, I don't think the issue is very clear cut in today's ruthless, win-now NFL. If a player comes off the bench, seizes his opportunity and plays considerably better than the incumbent, surely he deserves an extended run of games?
Philadelphia Eagles head coach Andy Reid obviously agrees - but only just.
Philadelphia's rival quarterbacks Kevin Kolb and Michael Vick
Reid liked young quarterback Kevin Kolb so much that he traded veteran Pro Bowler Donovan McNabb to the Washington Redskins in the off-season. But Kolb suffered a concussion in what turned out to be a shaky first half of the season opener against the Green Bay Packers and Reid turned to the rejuvenated Michael Vick.
Vick made the most of his opportunity, leading the Eagles to 52 points in six quarters of action against the Packers and Detroit Lions.
At the start of this week, Reid insisted Kolb would return as the starter for this Sunday's clash with the Jacksonville Jaguars. He has since undergone a complete turnaround and named Vick as his starter.
I think that is the right move. I don't agree with Reid's assessment that Vick is one of the best quarterbacks in the entire league at the moment but I do think he is the guy with the hot hand and brings more playmaking ability to the Eagles' table.
Some will begrudge Vick his chance to shine as an NFL starter once more. His story is well-documented - he shot to fame as a Pro Bowl quarterback with the Atlanta Falcons. He was inconsistent but exciting, blessed with a cannon for an arm and the speed and moves of a wide receiver.
But his career and life unravelled in 2007 when he was suspended by the NFL and found guilty of funding a dog fighting organisation in Virginia. America was sickened. He spent 18 months in prison before returning to the NFL as a backup for the Eagles in 2009.
When Vick returned to the playing field - in brief cameo roles with the Eagles last season - it was clear he was not in the same kind of physical shape as when he had starred with the Falcons. He attempted just 13 passes during the entire year.
But this season, he looks sharp and in great shape. You might not want to root for him to succeed in his second shot at the NFL, but it is hard to deny the fact that Vick has played very well in the last game and a half.
He can still tuck the ball away and scramble downfield when necessary, but what has impressed most - particularly last weekend against the Lions - was his ability to stay in the pocket and fire accurate passes downfield.
While there is no doubting the fact he has played well this season, Vick might benefit from the timing of this move in the long-term. Sure, he played well against the playoff-bound Packers, but he really shone in Week 2 against a Detroit team that has struggled to stop the pass for more seasons than I would care to remember.
And this week he gets to pad his statistics even more against a Jaguars team that is really not very good and has trouble pressuring opposing quarterbacks. Vick has taken his chance but Kolb must be frustrated, knowing he could also have performed well against the Lions and Jaguars.
Reid isn't prone to flip-flopping between quarterbacks so it was a bold move on his part to stay with Vick this week. And I think he has done this for a couple of reasons.
First, that Eagles offensive line is definitely a work in progress right now. Kolb came under pressure in Week 1 and he struggled to handle it given the fact he is pretty much a pocket passer.
Vick, on the other hand, is a very different matter. Force Vick out of the pocket and you will live to regret it. He has breathtaking speed and athletic ability and can leave the quickest of NFL defenders trailing in his wake. Given the fact that Philly quarterbacks will have to improvise and think on their feet at times this season, Vick would seem to be the obvious choice.

Second, Kolb just hadn't built up enough pedigree to be handed the job back no matter how Vick performed. He started a handful of games in relief of the injured McNabb last term but it was this 2010 campaign in which he was supposed to shine.
And he lasted just 30 minutes. Reid feels Kolb has a bright future with the Eagles but now the youngster has to be patient and wait for his chance. And maybe that shouldn't come any time soon because flipping between quarterbacks on a weekly basis is no way to establish offensive success.
Having made the move to Vick, Reid must now give him a run of games to prove his worth. And it will take a few weeks - or maybe even a season - for Vick to truly convince his doubters because even at the height of his success in Atlanta, he had regular spells of inconsistency and under-achievement.
Vick has an opportunity that he must have felt was beyond his grasp when he was serving his prison sentence in Kansas.
There are many who find it hard to cheer Vick's success, but you cannot deny his attempts to rescue his football career make for a fascinating sub-plot to this NFL season.
But Vick should know that he will need to prove himself each and every week. Reid has already shown he is willing to send his starting quarterback to the bench if necessary and I doubt he would think twice about doing it again in the future if the situation arose.

The Broncos could be without star cornerback Champ Bailey, who is nursing a high ankle sprain, and that spells trouble with Colts quarterback Peyton Manning boasting an embarrassment of receiving riches in Reggie Wayne, Austin Collie, Dallas Clark and Pierre Garcon.
Denver would love to run the football effectively in order to take time off the clock and keep Manning on the sidelines, but their running game has been spotty at best and they leant heavily on quarterback Kyle Orton during last week's win over Seattle.
If this turns into a shootout between the quarterbacks, the Colts will win at a canter. Even if the Broncos can find a way to make life difficult for Indianapolis, I still expect Manning's men to have too much firepower and I think they will grab their second win of this young season.
