One or two games do not define a career — unless you’re talking about a Super Bowl performance.

Still, Kevin Kolb’s legacy as a starting quarterback in Philadelphia could very well come down to this weekend’s game in Jacksonville — the place that started the beginning of the end of the Donovan McNabb era in Philadelphia. Sure, it took five years for McNabb to be shipped out of town, but the Super Bowl game really started the downfall.

Kolb’s career in Philly hangs in the balance this weekend? An overstatement, you say? Not really.

Kevin Kolb will return to the Eagles lineup on Sunday in Jacksonville in what could be a defining moment of his career.

Consider the fact that Kolb has not played well during the preseason or before getting his bell rung in the season opener against the Packers. Consider the fact that Michael Vick has played very well in six quarters this season. Consider the fact that there is now a quarterback “controversy” where there should be none.

If Kolb plays miserably and the Eagles lose to the Jaguars, the catcalls for Vick will only get louder. Nobody will care about the fact that he’s playing behind an offensive line held together with duct tape. Oh, and then he’ll have to deal with that and the return of McNabb to Philly in week 4. Talk about pressure.

The only way to take away that pressure is play well and win this weekend. Then, at least the Vick talk will fade to black for a couple of weeks.

Otherwise, he’ll face big-time adversity — something he has yet to show he can overcome.

Granted, you really can’t judge Kolb until at least midseason. Still, this is the NFL and this is Philadelphia. The same pundits who thought Kolb was a stud based on two games last season are the same ones who will trash him after two bad games this year.

Like it or not, this week may be the most important of Kolb’s career. And, it really isn’t an overstatement if you consider the situation he’s in.
