The quarterbacks

Michael Vick enjoyed his best practice since the Eagles opened training camp last week. He reeled off several nice runs after failing to spot some receivers and hit wide receiver DeSean Jackson for a pair of big gains. Nick Foles showed good command of the offense, but made one big mistake when his pass over the middle was intercepted by safety Colt Anderson. Rookie Matt Barkley continued to impress with his decision-making and accurate passing. "Matt may be a rookie, but he brings a wealth of experience," Eagles coach Chip Kelly said Wednesday. "He was a four-year starter in high school and a four-year starter in college. Plus, he's a football junkie. He eats it and he breathes it."

The new guys

Linebacker Connor Barwin is emerging as one of the leaders of the defense. Running back Felix Jones had a rough day, dropping passes on back-to-back plays. Rookie defensive tackle Bennie Logan was dominant in the pass-rushing drills.

Position analysis: Offensive line

Returning players: Tackles Jason Peters (starter), Dennis Kelly, Matt Kopa; guards Evan Mathis (starter), Todd Herremans (starter), Danny Watkins, Julian Vandervelde, Nate Menkin, Matt Tennant; centers Jason Kelce (starter), Dallas Reynolds.

Newcomers: Tackles Lane Johnson (starter, draft pick), Michael Bamiro (rookie free agent), Nic Purcell (rookie free agent), Matt Tobin (rookie free agent), Allen Barbre (rookie free agent), Ed Wang (free agent); center Kyle Quinn (rookie free agent).

Outlook: The Eagles were decimated by injuries up front last season, but now have Peters, Herremans and Kelce back. Peters is considered the best left tackle in the NFL. Herremans will be switching positions, moving from right tackle to right guard to make room for Johnson, the Eagles' first-round draft pick. Mathis had a very good season in 2012 and just missed a Pro Bowl berth. Having the steady Kelce back in the middle is a huge improvement.

If the season started today

Vick would be the starting quarterback. He has been the best quarterback on the field for the last two practices at the NovaCare Complex.

Play of the day

Vick capped Wednesday's practice with a 35-yard touchdown pass to Jackson in the corner of the end zone against cornerback Trevard Lindley.

What they're saying

Kelly, on the suggestion the team will try to take advantage of the referees: "It's like you're driving and the speed limit is 65. You may want to go 85, but if there's a cop out there, you won't do 85."

Bumps and bruises

Peters left practice Wednesday with what team officials described as a "mild hamstring" strain. Wide receivers Arrelious Benn (strained knee) and B.J. Cunningham (strained hamstring), defensive tackle Antonio Dixon (strained hamstring) and cornerback Cary Williams (strained hamstring) did not practice Wednesday.

Eagles today

They are scheduled to practice at the NovaCare Complex in front of approximately 400 invited guests at 12:30 p.m.
