The Dolphins' first depth chart of the season says everything is as expected. Monday's practices, however, showed that two of the Dolphins' three defensive back draft picks aren't hesitating to shove their way into the lineup.

The first depth chart of the season -- titled ``2009 MIAMI DOLPHINS TENTATIVE DEPTH CHART'' as if to emphasize how quickly it could become dated -- had veterans Will Allen and Eric Green still as the first-team cornerbacks, with second-round pick Sean Smith and first-round pick Vontae Davis as the second-team corners. But throughout Monday, Smith replaced Green with the first team.

Fifth-round pick Chris Clemons was listed as the third-team strong safety, behind Yeremiah Bell and Courtney Bryan. But Clemons not only has been playing with the second team all week, he had two interceptions and nearly a third in Monday afternoon's team drills. That's not to mention a big hit on running back Patrick Cobbs as Cobbs ran down the sideline on a sweep that got the defense hopping around happily.

``We want to shuffle the deck at the end of the first week, take a look at a week's worth of work that we had and mix some things up,'' Dolphins coach Tony Sparano said of Smith and defensive lineman Randy Starks playing with the first team Monday. ``See some different people versus different people.''

When asked if it had anything to do with Saturday's scrimmage specifically, Sparano said: ``The scrimmage, from an evaluation standpoint -- short of the competition part of the thing and maybe getting a chance to take a look at what was done over the week from a fundamental standpoint -- was just another part of the 11 practices that we have had. It is just combination of the entire week.''

On Monday morning, Smith stayed with speedy Ted Ginn Jr. on a deep sideline pattern during one-on-one drills and knocked the slightly under thrown pass away. Smith was still walking back up the sideline when Greg Camarillo, not known for his speed even before his season-ending knee injury, got behind Green on a similar deep pattern for a ``touchdown'' catch. It was the kind of contrast that seemed to emphasize the decision to elevate Smith.

``For the whole day, I think I did pretty well,'' Smith said. ``I didn't go in there feeling any different than when I first woke up. I did my assignments and made sure I didn't have any mistakes.

However, Davis still seemed to have problems making plays on the ball after providing good coverage. During a two-minute drill Monday afternoon, Davis had fellow rookie Brian Hartline sealed to the outside on a deep pass that was thrown just inside the pair. Hartline cut behind and inside Davis to gain position before dropping the pass.

``Go get the ball!'' defensive backs coach Todd Bowles yelled at Davis.

Two plays later, on a third down situation, Davis was fooled on a double move by ex-practice squad player Brandon London for a 20-yard gain over the middle that put the offense in position for a field goal.

``I think he has done some young-guy things -- got double-moved out here at [Saturday's] scrimmage right away,'' Sparano said.

``Really, got double-moved twice during the course of the scrimmage. [He] has shown to be very physical. He has catch-up speed, which is critical. Not afraid. Has a pretty short memory out there as a corner, which is good. There are some fundamental things out there we need to work on. He needs to get his eyes out of the backfield.''
