From the outside, it looks like Nick Foles is absolutely at the top of his game.

It’s impossible to imagine him playing any better. Heck, it's hard to imagine anybody playing any better.

He’s only the third quarterback in NFL history to throw 16 touchdowns in a season before his first interception. His 128.0 passer rating is the highest ever by a quarterback 11 games into a season. Despite starting only five games, he’s second in the NFL with 12 completions of 40 yards or more.

How can he possibly be more productive? How can he possibly improve?

That’s Bill Lazor’s job.

Making sure one of the hottest quarterbacks in NFL history continues to get better.

“As a coach, you’ve got to set a standard, and as he approaches it, you move it up,” Lazor said. “Just like you do with your kids. When he approaches it, you move it up. Just keep raising the standard.”

While the rest of us marvel at what Foles is accomplishing, Lazor -- in his first year as Eagles quarterbacks coach -- is responsible for focusing on what he’s doing wrong, what he needs to work on, what he needs to improve.

We can all say it’s hard to imagine Foles playing at a much higher level. But that’s all Lazor thinks about.

“We really don’t focus on the stats. Ever,” said Lazor, a record-setting all-Ivy League quarterback at Cornell in the early 1990s.

“We just focus on, ‘How did you play?’ We grade on accuracy, not on if it was a completion but if it was in exactly in the right spot. And when the guys in the room are doing it with you and they buy into it – ‘Yeah coach, I should do better than that’ -- you have a chance to keep getting better.
