Which Vick will Eagles get this season?

THE EAGLES will open training camp today at Lehigh with Mike Vick as their starting quarterback. If you're an Eagles fan, that should make you a little nervous. Excited, but also nervous.

It should make you nervous because, well, there's still an awful lot we don't know about Vick.

Yes, he played very well last year. Had career-highs in passer rating (100.2), completion percentage (.626), touchdown passes (21), total touchdowns (30), interception percentage (1.6) and yards per attempt (8.1).

But the 2010 season was a tale of two Michael Vicks. There was the early-season Vick, who came off the bench in Week 1 after Kevin Kolb suffered a concussion, and set the NFL on its ear, throwing 11 touchdown passes and no interceptions and putting together a league-best 115.1 passer rating in his first six games.

And then there was the late-season Vick. The one who had just an 84.4 passer rating in the Eagles' final four games. The one who had just a .586 completion percentage and seven touchdowns and five interceptions in 140 attempts in those four games.

The one who made that poor late-game decision to throw an up-for-grabs pass to rookie Riley Cooper in the Eagles' still-winnable playoff loss to the Packers, even though he had LeSean McCoy running free underneath. Tramon Williams intercepted the pass and the Packers hung on for a 21-16 win.

I'm not trying to be negative here. Vick came a long way last year in his development as a quarterback. A lot farther than I ever thought he would. Particularly when you consider how inconsistent the Eagles' offensive line was. Hell, he made the Pro Bowl.

But as defensive coaches gathered film on Vick and had a chance to see what worked against him and what didn't work, he wasn't nearly as effective in December and January as he was in September and November (he missed three games in October with torn rib cartilage).

Most of his improvement last year was the result of the hours and hours he put in last offseason with offensive coordinator Marty Mornhinweg, who taught him, really taught him, how to play the quarterback position.

Vick would've benefitted greatly from another offseason like that, particularly since, as the team's No. 1 quarterback, he would've been taking most of the reps in minicamps and OTAs, which wasn't the case last year when Kolb was taking those snaps. But the 136-day lockout kind of put a crimp in that plan.
