Even before watching him play well into the third quarter on Thursday night, there was no denying that veteran Ryan Fitzpatrick was in the lead to be Miami's starting quarterback in Week 1. That's seemingly been the road the Dolphins have been heading down all summer, even if first-year head coach Brian Flores continues to not name a starer. 

While Fitzpatrick still may be the guy come the opener, Josh Rosen, who was acquired by Miami in a trade with the Cardinals at the NFL Draft, was able to make case for himself in Thursday's 22-7 win over Jacksonville. 

Fitzpatrick got the nod to start the contest and was the beneficiary of two short fields that both resulted in Miami field goals in the first half. He came out of the locker room in the third quarter and did help lead the Dolphins on an 86-yard touchdown drive before handing things over to the former No. 10 overall pick in Rosen. 

The 22-year-old immediately took the Dolphins on a 99-yard touchdown drive and finished his night completing 5-of-7 pass attempts for 59 yards, while also rushing for 23 yards on four attempts. He didn't light the world on fire as he was facing inferior competition in the final minutes of a preseason exhibition, but certainly is giving Flores some pause before ultimately coming to a decision.
