QB Watch: Eagles' Michael Vick

A weekly analysis of the Eagles' quarterback play:

Rewind: Michael Vick's debut in Chip Kelly's offense was spectacular for one half and workmanlike for one half. Vick literally sprinted out to a great start, completing 13 of 21 passes for 190 yards and two touchdowns (rating of 123.1) as the Eagles built a 26-7 halftime lead. Vick also ran Kelly's zone-read, no-huddle system extremely well. He ran for a touchdown and broke a 36-yard run to keep an important drive alive. Vick threw for only 23 second-half yards as the Eagles ran the ball heavily.

Fast-forward: The world will be watching to see if Vick and the Eagles can duplicate their first-strike success against the San Diego Chargers Sunday at Lincoln Financial Field. The Chargers gave up 449 total yards, third most in the NFL, against Houston Monday night. They also blew a three-touchdown lead, as Matt Schaub passed for 346 yards and two touchdowns.

Hits and hurts: Vick took nearly 20 hits in Monday's game. That included three sacks, but also the nine planned and improvised runs when he chose to dive forward rather than slide and avoid contact. Kelly has already acknowledged that it's too late to get the 33-year-old Vick to change his ways and slide. Vick was limping late in the game with a groin injury, but is expected to practice Wednesday and be fine for Sunday.

Prediction: Vick's numbers will be dictated less by San Diego's vulnerable defense than by Kelly's play calling. The new coach likes to run the ball a lot, and LeSean McCoy's 31-carry workload Monday night was no fluke. That said, Vick should be as effective in the passing game as needed.
