t impact on Sunday's game between the Titans and Dolphins.Ryan Tannehill?Marcus Mariota?Luke Falk?Yes Womens Vincent Taylor Jersey , Falk, a fourth-string rookie who won't even play, has altered preparations by both teams. Miami signed him last week after he was released by Tennessee on cutdown day, and the Dolphins are sure to pick his brain about the Titans' scheme under rookie coach Mike Vrabel.All of which adds lends another layer of unpredictability to the season opener.Here are things to know about two teams who didn't excite preseason prognosticators:QB MATCHUPRyan Tannehill returns after missing the Dolphins' past 20 games, and says he'll be ready rather than rusty. He's coming off reconstructive knee surgery that wiped out his entire 2017 season, and says he never doubted he would be ready for the 2018 opener."I always felt confident that this would be where we ended up," he said. "It's finally here and I'm ready to go."While Tannehill has never played in the postseason, counterpart Marcus Mariota is trying to become the first quarterback to lead the Titans to the playoffs in back-to-back years since Steve McNair in 2002-03.That will require proving wrong the oddsmakers who predict Tennessee will win eight games. Miami, led by third-year coach Adam Gase, is widely projected to repeat last year's 6-10 record.THE OTHER QBWhile Falk will be able to provide the Dolphins some insight into Sunday's matchup, Vrabel says it could have been worse.The Titans' new coach wanted to install the entire offense during training camp, but offensive coordinator Matt LaFleur — mindful the team would have to waive some players — talked him out of it."He wanted to hold some stuff," Vrabel said. "I said Bobby McCain Jersey , 'OK, I'll defer to you on this one.' As it turns out, he was kind of right. There'll be some things that I'm sure Luke can give them. But then again, I am glad that Matt was adamant about holding some stuff until cutdown day. I think he had been burned by some of that stuff in the past."The Dolphins kept some of their playbook under wraps during the preseason, too. They're expected to have packages for veteran newcomer Albert Wilson and rookie tight end Mike Gesicki that they didn't show in exhibition games."There were a few plays going into Week 3 that Gase wanted to run," Tannehill said with a smile. "I said, 'Hey, those are great plays. Let's save those.' We have some things that we haven't shown that we're excited about."HOMECOMINGNFL active rushing leader Frank Gore will make his Dolphins debut, and at 35 he's thrilled to return to South Florida, where he was born and raised and starred for the Miami Hurricanes.Gore will play in his 113th consecutive game, and he needs 76 yards to become fourth-leading rusher in league history.HEY, I KNOW YOUMiami and Tennessee added former Patriots teammates during the offseason. Receiver Danny Amendola joined the Dolphins, while the Titans acquired cornerback Malcolm Butler. The Titans' other starting cornerback Jakeem Grant Jersey , Logan Ryan, is another Amendola friend and former Patriots teammate.Tennessee's secondary also includes All-Pro safety Kevin Byard and cornerback Adoree Jackson, who started every game as a rookie last year."We're super excited to see what we've got," Ryan said. "It's the most excited I've been to start a season off."STREAKING IN TENNESSEEThe Titans have won five consecutive road openers, the NFL's longest such streak. Three of those came in season openers. The streak includes three coaches, and three of the victories came by 16 points or more, including last year's 37-16 victory at Jacksonville in Week 2."The mindset is to win," linebacker Brian Orakpo said. "I mean, it's point blank, period, win. Win ballgames. Take it week by week and win, no matter if it's 50-49 or 3-0."Teresa M.

Could the starting quarterback for the Miami Dolphins in September 2019 be the same starting quarterback they had in September 2018? Could Ryan Tannehill continue to helm the Dolphins’ offense?It seems like it is more than a possibility at this point. The Dolphins were supposedly interested in signing former Cleveland Browns quarterback Tyrod Taylor, but he signed in free agency with the Los Angeles Chargers. Miami has hosted Teddy Bridgewater on a free agency visit, but no deal has been completed as of yet, and there were already rumors prior to the visit that Bridgewater plans to re-sign with the New Orleans Saints to serve as the backup and heir apparent to Drew Brees.Which leaves the Dolphins, who would like to get out from under the $26.6 million salary cap number for Tannehill in 2019, looking for a starting quarterback. The best choice is probably the guy on the roster. Who is the better option? Blake Bortles or Ryan Tannehill? Josh McCown or Ryan Tannehill? Ryan Fitzpatrick or Ryan Tannehill? Robert Griffin III or Ryan Tannehill? Add in that, unless the Dolphins use the post-June 1 option if they release Tannehill, the team is already committed to $13.4 million counting against them for the quarterback position - the dead money that it cost Miami with a release of Tannehill - the question becomes, does whatever a new veteran quarterback will demand plus that $13.4 be enough savings from Tannehill?The Dolphins seem intent on having a veteran starter this year, with the potential of adding a rookie in the NFL Draft. That could still happen with Tannehill.I have said it many times Albert Wilson Jersey , you do not get rid of your Alex Smith until you have your Patrick Mahomes. The Dolphins have their Smith in Tannehill, but they do not have their Mahomes yet. Maybe they can find a different Smith, but until they know that they have him, do you risk getting rid of the quarterback you know?It is a new coaching staff, and they probably want their guy to take charge of the team, but in a down year for draft prospects at the quarterback position, and a free agency pool that - other than Nick Foles - really would be headlined by Ryan Tannehill, is keeping Tannehill the right move for the Dolphins?It just might be.
