Josh Rosen knows what it's like to fend off criticism. Despite a rookie season in which he ranked as arguably the league's worst starting quarterback and a subsequent trade from the Arizona Cardinals, then, it should come as no surprise that the N0. 10 overall pick in the 2017 draft believes he has what it takes to be the Miami Dolphins' franchise signal-caller – both physically and mentally.

Josh Rosen came under fire during his three years at UCLA for his outspoken opposition to NCAA amateurism rules and widespread interest in non-football activities, including politics. His performance as a rookie, when he threw for 2,278 yards, 11 touchdowns, and 14 interceptions while completing just 55.2 percent of his passes, only provided more fuel for skeptics of his ability to thrive in the NFL.

But after being traded to the Dolphins on Friday in exchange for a second-round pick and fifth-round selection in 2020, in the wake of Arizona selecting Oklahoma quarterback Kyler Murray with the No. 1 overall pick, Rosen has a golden opportunity to reset his career with a team that should be comfortable giving him time to develop on the field. Still, that doesn't mean he won't have to compete to become the Dolphins' long-term answer at quarterback.

“You have to earn the right to get that kind of label,” Miami coach Brian Flores said of anointing Rosen as the team's “franchise quarterback,” per ESPN's Cameron Wolfe. “You have to do it in the meeting, on the practice field. To label a kid like that right off the bat, I feel like that's unfair in a lot of ways. You have to earn it.”

The Dolphins, after trading away incumbent starter Ryan Tannehill, signed veteran signal-caller Ryan Fitzpatrick to a two-year, $11 million contract in March. Expect he and Rosen to compete to be Miami's starter throughout offseason activities and training camp.
