Dissecting sacks vs. Eagles so far

Offensive coordinator Marty Mornhinweg acknowledged yesterday that one reason the Eagles have given up 25 sacks so far this season, vs. 23 all last season, is that Donovan McNabb was being more mindful of getting the ball out last year.

"As you go through sacks, in my history, two-thirds of the sacks are normally [on] the quarterback, there is a chance to get the ball out. [In] only about a third is there absolutely no chance to get the ball out," Mornhinweg said. "I thought he did an excellent job of that last year. Two of the [sacks in the Bears game] were on screens. We talked about this - some of those guys are faster than you are now. Back in the day, you could move and groove and make 10 yards. But two of them were on screens, so we have to throw [the ball] away. I'm not particularly concerned about that, because we know where the issues were, so we have that corrected just a bit."

McNabb turned 33 on Wednesday.

Cornerback Asante Samuel (neck) and linebacker Akeem Jordan (knee) did not practice yesterday. Cornerback Sheldon Brown was a limited participant . . . Special-teams coordinator Ted Daisher said he isn't sure whether Macho Harris or Quintin Demps (ankle) will return kicks this week . . . Asked about Sav Rocca's 16-yard punt in Chicago, Daisher said: "We expect Sav to be more consistent than what he has been. He has worked hard throughout the season and he's going to have to do a better job this week for us." Daisher acknowledged the Eagles have emphasized directional punting, with injuries changing the cast of gunners in coverage every week. *
