ack with the Miami Dolphins is headed into overtime.Coach Adam Gase declined to say Sunday whether Brock Osweiler or David Fales would be first off the bench to replace Ryan Tannehill Mark Clayton Jersey , but the coach said he expects to keep all three quarterbacks all season.The margin between Osweiler and Fales was thin during training camp, Gase said.“It’s day to day,” he said. “I feel like it goes back and forth. It’s one of those things — whoever has the best protection on that particular night, it seems that guy has a good night in preseason. That’s what is always going to make it tough deciding who’s the backup. You’re guessing a little bit.”More Miami Dolphins newsDolphins sign hometown WR Allen Hurns to 1-year contractNew Dolphins coach Brian Flores has his own daily workout at training campDolphins assistant coach Jim Caldwell takes leave of absence to address health issuesTwo-time Pro Bowl safety Reshad Jones rejoins Dolphins after skipping voluntary practicesDolphins QBs Josh Rosen, Ryan Fitzpatrick embrace battle for No. 1 jobGase said he may list the No. 2 quarterback as “Osweiler or Fales” on the depth chart preceding the season opener Sept. 9 against Tennessee.The Dolphins are underdogs at home, and coming off a 6-10 season in 2017, they’re widely projected to finish below .500 again. But in the wake of cuts to reach the 53-man roster limit, Gase sounded as optimistic as every other coach at the end of the preseason.Roster turnover has resulted in a better locker-room culture Adam Joseph Duhe Jersey , Gase said, and he anticipates the improvement to be reflected in the win-loss record.“I like our team. We’re a team,” he said, emphasizing the last word. “That’s the best part about what we have going on right now — that locker room. I’m not really worried about what anybody else thinks about that. When you’re not there every day and around these guys, you don’t know. You can look at a piece of paper, but that’s why they play the games.”Miami should be better at quarterback, with Tannehill returning after missing last season following left knee surgery. But it’s unclear whether holdover Fales or newcomer Osweiler represents an upgrade over the departed Matt Moore, who had been Tannehill’s backup since 2012.The play of both Osweiler and Fales was spotty during training camp. Gase works closely with quarterbacks and saw enough potential to want to keep them around.“You talk about that being one of the most important positions Larry Csonka Jersey ,” Gase said, “and our thought process is we’re going to try to develop guys and get them ready to go. And if we’re ever in a situation where we need the next guy, we want to make sure we have the right guy. And we’re going to keep working with the two guys we’ve got.” With quarterback Marcus Mariota in the final year of his rookie contract and given that the Titans have yet to decide to make a long-term commitment to the second overall pick in the 2015 overall draft, the Titans need to be thinking about the future of the position.Maybe the future is closer to now than believed.Ryan Tannehill has arrived, and the Titans have embraced him as No. 2 on the depth chart.“He understands that he’s coming in as the backup quarterback,” G.M. Jon Robinson told reporters on Friday regarding Tannehill. “I’ve talked to Marcus and told Marcus he is our starting quarterback. Ryan is here to help Marcus, to push Marcus, to compete with Marcus. One thing after talking with Marcus Dan Marino Jersey , he said, ‘You know, one thing Jon that I believe with all my heart is that you to do what’s best for our team and try to put us in position to win football games.’ That made me feel pretty good.”Having Tannehill around also makes Robinson feel good, in the event that Mariota gets injured or otherwise struggles. Tannehill hasn’t been horrible, he just hasn’t been healthy. And if Mariota isn’t healthy for a game or two this year, Tannehill will have a better chance to push the team to a win than Blaine Gabbert.
