New Miami Dolphins assistant coach Chad O’Shea has at least 22 years of college and NFL coaching experience under his belt, including the last nine years grooming wide receivers for the New England Patriots.

However, for the first time in his career, he will be an NFL offensive coordinator. And he will ultimately determine who emerges from the Dolphins’ starting quarterback competition.

That challenge could be daunting for O’Shea, considering the last quarterback he has primarily worked with in a football practice was Tom Brady — the six-time Super Bowl champion and one of the greatest players to ever play the position.

But there will be a deciding factor O’Shea will consider when determining if second-year quarterback Josh Rosen or 14-year veteran Ryan Fitzpatrick should lead the offense next season.

“I think the first thing is a leader,” said O’Shea, one of 13 Dolphins assistant coaches to meet with media Thursday. “You want someone who they see as their leader. You want somebody to be the ambassador of your program — a flag bearer, basically.

“Somebody that you trust to carry on the message of what your vision is from coach [Brian Flores], from the offensive staff thorough the team, so I think leadership is very important.”

It’s been two weeks since the Dolphins acquired Rosen on a draft-day trade on April 26, and roughly two months since Fitzpatrick signed as a free agent with Miami.

Both moves were made after the Dolphins parted ways with seven-year starter Ryan Tannehill, who was traded to the Tennessee Titans.
