If Fitzpatrick sustains an injury and/or Tagovailoa is not ready to play as he continues to recover from his hip injury, Rosen's availability could be vital to the Dolphins season.
If Tagovailoa and Fitzpatrick are healthy, however, Rosen's playing time could be non-existent.
Rosen's potential trade value, which could be estimated as a third-day draft pick, could rise if another team loses their starting quarterback to an injury or COVID-19 concerns.
Rosen is still a relatively cheap and talented option to have on the roster. He is owed roughly $2 million in 2020 and $2.8 million in 2021, which are both fully guaranteed.
Also, Fitzpatrick is in the final year of a two-year deal he signed with Miami, which will pay him $8 million this season.
If the Dolphins trade Rosen and Fitzpatrick retires or signs with another team next year, Miami could be looking to replace two quarterbacks to back up Tagovailoa in the immediate future.
As for Tagovailoa, who received a glowing endorsement from Fitzpatrick last weekend, Flores would not specify how he has looked solely from strength and conditioning drills.
Team workouts, including 11-on-11 drills, is likely to begin on Aug. 17, which Tagovailoa could need further clearance from team doctors to participate in.
"Tua and our entire rookie group, they're doing well," said Flores. "I feel like to speak about one and not speak about the entire group is ... I mean, they're all working really hard. I think we've got a pretty solid group.
"As far as anything past their height, weight, speed, we're not really seeing them move, change of directions, really sprint. We're really not seeing that from anyone in my group, including Tua," Flores added.
" ... As practice starts to ramp up and we more into the OTA and actual practices, we'll really get an evaluation. Right now in a walkthrough setting, we're not really seeing all that much."
