PHILADELPHIA -- Everybody seemed to have an opinion about Chip Kelly's fast-break offense after its NFL unveiling on "Monday Night Football."

Kelly was no exception.

"I felt like it was slow," the first-year Philadelphia Eagles coach said Tuesday. "I'm not joking. We need to do a better job.

"We left the ball on the ground too much. We didn't get the ball to the officials. We could have sped things up from a process in between plays. That's something we need to work on."

The Eagles ran 53 plays in a frenetic first half against the Washington Redskins' stunned defense, amassing 322 total yards. Philadelphia had as many first downs (21) as Washington had offensive plays and entered halftime with a 26-7 lead. The Redskins' only first-half score came on a 75-yard fumble return.

The Eagles ran a play every 22.2 seconds -- and Kelly thought it was slow?

As it turned out, Eagles center Jason Kelce, who along with the quarterback has the most responsibility for dictating tempo, felt the same way.

"I know we can go faster," Kelce said. "I think we went at a really good speed. There were times when we really put the foot on the pedal and were flying around out there, and there were times we eased it back a little bit. We definitely have plays we can still go faster with."

Kelce also hinted at the second issue raised by the game -- what happened to that go-go offense in the second half?
