Here is the good news for the Miami Dolphins: They have a roster stacked with under-25 talent that positions the team well for the next few seasons.
Here is the bad news: Miami is in a must-win year in 2015, and the coaching staff and front office need its young talent to produce immediately.
That sums up the current state of the Dolphins. This is the most talented team Miami's had in years, but a good portion of its talent is young and needs more experience.
According to Football Outsiders, the Dolphins are ranked No. 2 in under-25 talent. Running back Lamar Miller (24), right tackle Ja'Wuan James (23) and receivers Jarvis Landry (22) and Kenny Stills (23) lead the way on offense. Starting defensive end Olivier Vernon (24) and potential starting cornerback Jamar Taylor (24) are on Miami's defense. All of these players are expected to have sizable roles this year.
