Josh Rosen played most of Thursday night's preseason game for the Miami Dolphins and Brian Flores came away with some impressions.

The new coach wants to see Rosen take fewer chances.

"At some point as a quarterback, you have to take a sack. That's the play," Flores said. "But the guy has a little bit of a gunslinger mentality and likes to let it rip. Obviously, that was a nice one to Preston [Williams], but I think we want to play smarter than that in that situation. Not just let the ball go like we did."

The second-year quarterback had no issue with what Flores had to say.

"You just can't fall into that trap because bad games will turn really bad really quickly if you don't learn negate that risk," Rosen said. "I've been battling that my whole career. I have to find that balance of knowing when I can push the edge, and when to just take the sack and live to play another down."
