DAVIE Kalen Ballage Jersey , Fla. (AP) — As Josh Rosen dropped back to pass during practice Tuesday, Ryan Fitzpatrick slapped and pushed him in the back, like an older brother trying to annoy.It was part of a drill, and those are the only swipes the two Miami Dolphins newcomers are taking at each other as they begin competition for the No. 1 quarterback job.Fitzpatrick, entering his 15th NFL season, has been through it all before. This year he can become the first player to throw a pass for eight teams.“I’ve always had to earn every opportunity that I’ve received,” said Fitzpatrick, 36. “I love the competition. I love being out here and trying to be the best me I can be.”When Fitzpatrick signed an $11 million, two-year deal in March, the job appeared to be his to replace the departed Ryan Tannehill. Then the Dolphins traded two draft picks for Rosen, who had a rocky rookie season in Arizona last year but could become the franchise quarterback Miami has sought since Dan Marino retired 20 years ago.Fitzpatrick, speaking publicly about the Rosen trade for the first time, said he took the deal in stride.“I’m here because this was an opportunity where I would have a chance to play,” Fitzpatrick said. “It was a job that was open.”It still is, according to first-year coach Brian Flores. He said the best QB in practice will start.“I expect Ryan to compete for the starting position,” Flores said. “I expect him to lead in the quarterback room, and really the entire offense. Obviously he has a wealth of knowledge and a lot of experience. There’s competition, but at the same time we’re trying to build a team and try to help each other become the best version of ourselves on the field. I expect him to be the leader he is. He has done a good job of that so far.”Rosen Durham Smythe Jersey , like Fitzpatrick, has embraced the battle for the No. 1 job, and said he’ll be mindful of the example set by his more experienced teammate.“He likes to goof around, but he works really hard,” Rosen said. “He has been in this league a long time. If I can take just a couple of lessons from him, they’ll do me very well in the long run.”The QBs’ lockers are side by side, allowing plenty of opportunity for conversation — such as when the cerebral Rosen explained to Fitzpatrick the ecological benefit of the recycled plastic in his cleats.“Some of the stuff he talks about reminds me of some classmates I had in college,” said Fitzpatrick, a Harvard alum. “The topics are sometimes not necessarily things I want to talk about. But he’s definitely an interesting guy.”This week’s practices are the first for Rosen with Miami. He fumbled three snaps to start Tuesday’s workout, and threw an interception at the beginning of seven-on-seven drills, while Fitzpatrick lined up with the first unit.Rosen acknowledged there’s a considerable learning curve in a new city with a new team.“My head is swimming,” he said. “You kind of underestimate from the outside looking in all the logistical issues — just having to move, and I’m walking into the receiver room thinking it’s the bathroom. There are a lot of little things that go into it. When you step on the field, you’ve got to let that go.”Fitzpatrick has been with the team only a few weeks longer but already seems at home. He led teammates jogging through an agility drill, holding the ball in one hand as defenders tried to poke it out, while repeatedly touching the turf with his other hand.Fitzpatrick reached the finish and struck a Superman pose. Rosen’s challenge will be to top that.NOTES: Two-time Pro Bowl safety Reshad Jones is skipping this week’s practices, which are voluntary. Jones also missed three voluntary workouts in April. Flores didn’t give a reason but said he has talked with Jones, and the continued absences aren’t an issue. Flores said he expects Jones to attend mandatory minicamp in June. … Cornerback Xavien Howard said he doesn’t plan a spending spree after signing a $76.5 million Jerome Baker Jersey , five-year extension , the most lucrative deal ever for an NFL cornerback. “I’m going to save it,” he said.Ravens at Dolphins: What to watch for Miami in 2018 Preseason Week 3 The Miami Dolphins will host the Baltimore Ravens tonight in the third week of the preseason. This game should feature the starters for both teams more than any other game during the preseason, with the clubs using this as a chance to make sure everything is ready for the regular season before protecting their key contributors next week during the fourth preseason game. A lot has to be answered still for the Dolphins, and hopefully this game will give us all a better understanding of what will happen this year.After a 10-6 season in 2016, landing in the playoffs, the Dolphins regressed in 2017, falling to 6-10 in one of the most unusual seasons ever. Included in the insanity was the training camp/preseason loss of both the offensive play caller, quarterback Ryan Tannehill, and defensive play caller, then-rookie linebacker Raekwon McMillan. Now, as the team looks toward 2018, they have both of those players back and will hope that is a big part of their struggles from last season.What should we be watching for in this week’s game? Those two are a big part of it.1. Ryan Tannehill, David Fales, and Brock Osweiler.Tannehill has to prove the offense is ready for the regular season. He has played fairly well so far this preseason, at times making throws that look like there is still some rust to work out, but solid play thus far. The offense has proven it can speed up the tempo of play and they have shown they are capable of moving the ball up-and-down the field. The problem is, they have not shown they can score yet. Miami is relying on field goals a lot during the preseason. Part of that is head coach Adam Gase admitting they are not calling red zone offense plays Mike Gesicki Jersey , but at some point, the first team has to get the ball into the end zone.Behind Tannehill, Fales and Osweiler need to establish who will be the backup quarterback this year. Fales jumped out to an early lead, but Osweiler has not gone away. One of the two of them need to come out hot tonight and show they are the player Miami can rely upon should the need arise.2. LinebackersMcMillan is a large part of this, and he needs to quickly move from looking like a player on the field for the first time on defense - which he is, but has to get through that - and start looking more like the middle linebacker in charge of the defense. Maybe it is unfair to McMillan, but it is what is needed right now.Next to McMillan, Kiko Alonso resumes his role on the outside and he is healthy, so hopefully he will be able to compliment McMillan and be ready for a better 2018. Rookie Jerome Baker appears to be the other starting outside linebacker, but he is going to make rookie mistakes. The linebackers as a whole have to come together and figure out how to support each other and the defensive line, and tonight may be the best chance for them to figure that out astray will likely see the most game snaps they will see this year.Behind those three, players like Stephone Anthony, Chase Allen, and Quentin Poling need to step up and show they can be the depth options Miami will need at some point this year.3. Mike GesickiThe Dolphins have not really involved rookie tight end Mike Gesicki much this preseason. He was targeted twice in the team’s preseason opener, but was overthrown both times. He was not targeted last week. The Dolphins have seemed to be more interested in having Gesicki block in the preseason, working on his technique and giving him experience there, but at some point, the team is going to have to get him involved in the passing attack more than just in practice. 4. Defensive tacklesThis almost feels like the same situation as the linebackers Cameron Wake Jersey , where younger players are being asked to step up and perform, and now they need to do it. Jordan Phillips has been battling an injury, but Davon Godchaux and Vincent Taylor need to step up and prove that they can be a starter and a depth option, respectively. Akeem Spence should be locked in as one starter, with either Godchaux or Phillips playing in the other spot. Whatever the case, the team was gashed up the middle last week against the Carolina Panthers, and they need to show that they can plug up those holes this week against the Ravens.5. CornerbacksA few weeks ago, it appeared the Dolphins were set to have a dynamic set of cornerbacks, with starting caliber players buried behind other starters on the depth chart. Now, Xavien Howard is one starter, and the rest of the group is a mess. No one seems to want to claim the other starting position. After allowing Cordrea Tankersley, Tony Lippett, and Torry McTyer all have shots as the top player opposite Howard, Miami last week moved nickel cornerback Bobby McCain outside, with rookie safety Minkah Fitzpatrick moving up to play in the nickel. Will that combination actually work? Will someone else finally step up and claim the spot? The Dolphins need to get this settled and tonight would be a great time for that.Honorable mention: PenaltiesWe have talked about penalties a lot, especially pre-snap penalties. Miami needs to get them under control.
