Garrard atop Dolphins' first depth chart

Not surprisingly, David Garrard is atop the first Miami Dolphins depth chart for training camp in 2012, according to NFL.com.

Garrard has been getting the lion's share of the first-team reps thus far in training camp, and is the odds-on favorite to be the team's opening day quarterback.

Matt Moore, the Dolphins starter for most of 2011, is listed at second-team, while rookie Ryan Tannehill, Miami's first-round pick, is currently running third team.

Coach Joe Philbin told NFL AM what Tannehill needs to do in order to move up the depth chart and become the starter.

First and foremost, he's gotta be a decision-maker," Philbin said after taking time to note that to be a great decision-maker takes time, experience and a quarterback's understanding of his own system, as well as, what the opposing defense is doing.

"Second thing is, if you're going to play quarterback in the NFL, you gotta make plays at critical times to win games," Philbin said. "That's something that, you know, we try to simulate the best we can on the practice field. We've been doing that, and obviously the preseason will give us another opportunity to gauge how far along he is in his development.

"The third thing is the game management," Philbin said. "That's obviously critical. Can he handle the pressures, the audibles, the checks, the time clock, etc.? ... Those are all factors that we've got to weigh in. And the last thing is does he have the respect of his teammates, which I think all of those candidates, as well as Pat Devlin, are guys that are highly-regarded by his teammates."
