What happened on the Peterson TD?

Posted by ESPN.com's Matt Mosley

MINNEAPOLIS -- The Eagles had done a nice job of setting the edge against Adrian Peterson and not giving him any cutback lanes -- until that last run. The Vikings had everything pointed toward the right side and then Peterson spotted a massive lane and cutback to his left for a 40-yard touchdown.

Looked like linebacker Chris Gocong had the only legitimate shot at bringing Peterson down, but there's no way you arm tackle this guy once he gets to the second level. Meanwhile, on the ensuing drive, Donovan McNabb just completed a ball to Kevin Curtis into tight coverage.

And while we're in a timeout, let's talk about how predictable the Eagles' offense is at times. Other than the one long run by Correll Buckhalter, there hasn't been much available on the ground. But part of that is the fact that the Eagles almost always seen to run on second down. At some point, it might not be bad to mix in a run on first down to keep the Vikings honest.

Well, DeSean Jackson just completely burned Vikings cornerback Marcus McCauley on a deep ball down the sideline. Everyone wanted to know how Jackson would perform in his first playoff game. So far, so good.
