Todd Archer's practice observations

* Rob Ryan will be aggressive. In the morning walkthrough, he sent Mike Jenkins off the corner on a blitz and did the same with Terence Newman in the afternoon.

* Liked what I saw from rookie FB Shaun Chapas as a pass catcher, reaching out for one pass, but he needs to keep his feet moving when he engages as a blocker.

* Rookie WR Dwayne Harris had a "Welcome to the NFL" moment when a Tony Romo bullet on a slant went through his hands. Later, he was quick to grab a slant from Jon Kitna.

* At one point, all three inside linebackers -- Keith Brooking, Bradie James, Sean Lee -- were on the field at the same time.

* OLB Victor Butler struggled in coverage in his first two years, but he had two pass breakups in 7-on-7 drills on passes to TE John Phillips and Chapas. Butler also had a would-be sack.

* Romo’s final pass of the day came on a deep ball to Miles Austin while rolling to his right. Rookie safety Collin Zych let out a groan as he saw Austin run by him for what would have been a touchdown.

* Defensive linemen have been told to get their hands up in the passing lanes if they can’t get to the quarterback. Jay Ratliff batted down a ball, as did Sean Lissemore.

* Felix Jones took most of the first-team runs, but Tashard Choice took a handful as well. He showed nice patience on his first carry but not too much patience in getting through the hole, keeping a hand on his lead blocker as he ran.

* The Romo-to-Jason Witten combo looked just fine. Witten came up with a one-handed grab along the sideline while being blanketed by a defender.

** This just in: DeMarcus Ware can play. He snuffed out at least two reverses, a run up the middle and was a constant threat in the backfield, too.

** Savvy move by the coaches to run the first- and second-team linebackers and secondary at the same time to speed up the learning process considering the players missed the offseason. Ryan worked with the first team. Linebackers coach Matt Eberflus took the second team. Joe DeCamillis and Chris Boniol did the same during special teams drills.
