Brian Flores did not wait long to name veteran Ryan Fitzpatrick the Miami Dolphins starting quarterback for their third preseason game. But that does not mean Flores is ready to name Fitzpatrick as the team’s starter going into the 2019 season.

Flores, speaking Monday ahead of Thursday’s home against the Jacksonville Jaguars, said he is still evaluating the position battle between Fitzpatrick and second-year quarterback Josh Rosen as the preseason nears its end.

Rosen, the No. 10 pick in the 2018 draft that was acquired in a trade with the Arizona Cardinals in April, still has an outside chance to win Flores over.

“I think he has to continue to improve in the things he’s done well, and the things he hasn’t done well. We need to see improvements,” Flores said of Rosen on Monday.

“He can’t take as many sacks as he’s taken in practice and in games. He’s got to step up in the pocket. He’s got to have command of the offense. And I think those things are very important at this position. He’s got to get the ball out quicker. He has to do all those things.

“At the end of the day, it’s about our offense moving the ball and putting points on the board.”

Despite playing with the starters during the second preseason game against the Tampa Bay Buccaneers last week, Flores quickly demoted Rosen back to the second team after the game.
