DAVIE, Fla. -- The first week of training camp is a time of immense optimism in the NFL. Every team is undefeated and believes it is worthy of the playoffs. Teams highlight strengths, not weaknesses, until the games matter in the regular season.

The same goes for Miami Dolphins third-year quarterback Ryan Tannehill, who is thinking big this upcoming season. Tannehill has lofty goals for himself and the Dolphins in 2014.

"We want to play deep into January and February," Tannehill said. "And that’s our goal at this point, is to go out, win the division and then play the playoffs from there. There is a big season ahead of us and I think anything less than that is not up to our standards."

Tannehill must set the tone for Miami. The previously mild-mannered quarterback is starting to be more vocal and make his presence felt. Tannehill is showing more emotion. This summer he screamed at a pair of receivers for making mistakes in practice, which is something the Miami media hadn’t previously seen.

The Dolphins are learning a new offensive under first-year coordinator Bill Lazor. Tannehill has to be an extension of Lazor on the field.

“One thing he has been doing, I tell people all of the time that he’s been a lot more vocal, taking a lot more control over this offense and over the team in general,” Dolphins tight end Charles Clay said. “You can see it in times like that, but he’s maturing a lot.”

It’s also clear the Dolphins are 100 percent behind Tannehill. He is just 15-17 as a starter and Miami averaged just 19.8 points per game last season.

But Tannehill has received universal praise from his teammates, who believe Tannehill is due for a breakout season. The quickest way for Miami to improve is for Tannehill to take the next step. The Dolphins have talented pieces in other positions and consistent quarterback play would take the team to a new level.

“I definitely think he has it,” Dolphins receiver Mike Wallace said of Tannehill. “The thing I love about Ryan is his composure. I don’t think he ever gets rattled. I’ve never seen it, personally. He’s good at coming back like it [a mistake] never happened and that’s what we need from our quarterback.”
