Kelly on Vick sliding, Casey sitting

PHILADELPHIA -- Chip Kelly raised a lot of eyebrows on Monday night. He raised a few more Tuesday when he said his offense looked “slow” in his eyes.

Here are some other highlights from Kelly’s first day-after news conference as head coach of the Eagles:

Michael Vick shouldn’t block, but forget about him learning to slide.

“Those are not by design,” Kelly said of the times Vick did his fullback impersonation. That tended to happen when LeSean McCoy would start to one side, then make a dramatic cut the other way. Vick was often the only Eagle in the area, and he threw a few solid blocks.

For a guy with an injury history, that’s probably not a good idea.

“We tell Mike not to do it,” Kelly said. “It’s simple.”

Vick also takes more hits than necessary because he dives forward at the end of runs instead of sliding feet first.

“I think that’s the way Mike likes to do it,” Kelly said. “I think that’s way he’s going to do it. We can put him in a little bit better situation. I’m also realistic. I don’t think, at 33, we’re going to get him to hook slide.”

James Casey may be on the sideline, but he’s not in the doghouse.

It was surprising how little Casey played in the preseason. Some of us thought maybe that’s because Kelly was hiding how he planned to deploy the free-agent tight end from Houston.

If so, he’s still hiding him. Casey was on the field for only a couple of plays against Washington. Kelly said that was about personnel groupings and game planning.

“We ran a lot of '11' personnel last night,” Kelly said. “In '11' personnel, he’s not in the game. A lot of times, that dictates what they do. They have more DBs in the game. It has nothing to do with James’ ability or whether we’re happy with him. Sometimes we’re going to feature three tight ends prominently.”

Clearly, Casey is behind veteran Brent Celek and rookie Zach Ertz. That is a bit of a surprise.

Vinny Curry was inactive for similar reasons. Kelly said Curry, who looked very good at pressuring quarterbacks in the preseason, simply fell victim to numbers. The Eagles dressed six defensive linemen and he was the sixth.

Considering how well the Eagles contained Alfred Morris (45 yards on 12 carries), it’s hard to argue with that.

• Cornerback issues continue. The Eagles re-signed Brandon Hughes Tuesday, which was the plan all along, Kelly said. Hughes was released Saturday only so his 2013 salary wouldn’t become fully guaranteed by his being on the roster Sunday.

Hughes, who broke his hand in camp, is cleared to practice Wednesday, Kelly said.

Good thing, because starting corner Bradley Fletcher sustained a concussion Monday night. His availability will be determined by the NFL protocol, which makes him unlikely to play against San Diego Sunday.
