You bet Josh Rosen has a monster chip on his shoulder

DAVIE – Josh Rosen acknowledged he’s got a lot to prove as the starts fresh with the Dolphins, not just to his new team but to all the critics of his rough rookie season with the Cardinals.

Dolphins general manager Chris Grier said after the trade to acquire the quarterback from the Cardinals that he expected Rosen to come to Miami with a chip on his shoulder.

“I don’t think my chip’s got to grow any more, I might tip over,” Rosen said with a smile during his introductory media conference Monday.

Rosen avoided sounding cocky but made it clear he is confident despite his struggled with Arizona. Asked if he still believed he can become the franchise-caliber quarterback the Dolphins have been seeking for two decades since Dan Marino retired, Rosen said, “Yes, because I think I am a good quarterback and I think I am a good leader.”

He indicated he understands that attaining that level in the NFL is an endless challenge.
