It has been so long since they had a Pro Bowl quarterback that Rosen referred to him as "Mr. Marino."Despite a rough rookie season that prompted the Arizona Cardinals to discard him, Rosen still believes he can be a Dan Marino-type franchise quarterback. And he's glad to get an opportunity with the Dolphins, who are eager to stop a revolving door at the position that has gone through 19 starters since Marino's last game 20 years ago."I couldn't be more excited to be here," Rosen said. "Very rarely do you get a second chance to make a first impression."As for motivation, Rosen's crooked grin grew wider when he was asked about any chip on his shoulder."I don't think my chip has to grow any more," he said.

Doubts about his leadership and personality linger despite efforts by Arizona teammates and coaches to dispel them.He said the issue dates to his years at UCLA."I didn't have all my answers as perfectly crafted as I do now," he said. "I said some things off the cuff, and people misconstrued them. ..."I think I'm a really good teammate. What I've tried to do is not say or do anything extra, just kind of be me and keep my head down, and eventually the story will straighten out. I think it has for the most part. Time and consistency are the best medicine to cure the narrative."With that in mind Chandler Cox Miami Dolphins Jerseys , Rosen had answers ready when asked about:— competing for the starting job with another Dolphins newcomer, veteran Ryan Fitzpatrick. "The timing on whether I play or not is not up to me."— Pro Football Hall of Famer Marino. "Hopefully I can follow in some semblance of his massive footsteps."— his belief that he can become a franchise QB. "I think I'm a good quarterback, and I think I'm a good leader."The Dolphins hope he's right.
