##Yesterday it was third-year wideout Roberto Wallace making all of the noise with the first team offense, so today was Marlon Moore’s chance. He lined up opposite Legedu Naanee and out his speed on display in the deep passing game, making a case for himself in what can now be characterized as a wide-open battle.

“There’s going to be good competition and I think we have some good players there,” Head Coach Joe Philbin said. “Once again part of my job is to develop players along with our offensive staff and our receivers coaches. That’s what we get paid to do and part of it is we’ve got to make good decisions based on the people that we have on the roster at this point in time. We’ve got to have some faith in them that they’re going to develop and they’re going to perform at a certain level. … I’m confident we’re going to get good receiver play here.”

##The three quarterbacks healthy at this time – Matt Moore, Ryan Tannehill and Pat Devlin – got a lot of work again in the absence of veteran David Garrard. Tannehill and Moore split snaps with the first team and made some good throws at all levels, short, medium and long.

##Tannehill continues to look good throwing on the run as he connected with Davone Bess early while being chased from behind. He also hid the ball well on play-action fakes and executed clean handoffs.

##When Moore came in with the 1s during a red zone drill he benefited from a circus catch by running back Reggie Bush just over the goal line with Koa Misi in coverage. Bush tipped the ball to himself, and then Moore came back with a perfectly placed fade pass to Bess in the left corner of the end zone.

## Punter Brandon Fields never ceases to amaze not only with the distance he gets on his kicks but the accuracy inside the 20. He launched a few bombs over 60 yards and put on that unique spin and touch to allow the ball to settle where it landed, getting good protection up front and good coverage down the field.

##Miami’s front four performed well against the run with their backs up against their own end zone, as defensive end Jared Odrick stuffed Bush at the line of scrimmage on one running play.

##Second-year running back Daniel Thomas looks quicker than he did at this time last year when he was dealing with a hamstring injury. He took one draw play and went untouched into the left corner of the end zone, showing a nice burst into the hole.

##Philbin and his staff conducted the practice one player down for the second straight day but did not rule out filling that vacant spot before the team leaves for Charlotte, N.C. on Thursday in advance of the second preseason game at the Carolina Panther.

CBSSPORTS.COM’S PETE PRISCO IN THE HOUSE: The train of national writers making their way to Davie continued today as Pete Prisco of CBSSports.com showed up to watch practice.

Prisco is based out of Jacksonville and had intended on coming down tomorrow but decided to get a leg up on his Dolphins homework. Had he come a day earlier he would have experienced a not-so-fun thunderstorm that interrupted yesterday’s practice.

“Quarterback, quarterback, quarterback. It’s always about the quarterback,” said Prisco when asked what he was watching the closest. “I also heard a lot about Coach Philbin’s practices and that he runs a quick-tempo practice, which I like. Why waste time?”
