The Miami Dolphins have 89 players on their roster, counting the signing today of wide receiver Tommy Streeter. The average age of those players is just 24.8 years old, the fifth-youngest team in the league. Only the Jacksonville Jaguars (24.5), St. Louis Rams (24.5), Green Bay Packers (24.6), and Houston Texans (24.8) are younger than Miami at this point in the offseason.
Miami has just eight players who have reached their 30th birthday already: cornerback Zack Bowman (30), quarterback Matt Moore (30), tackle Branden Albert (30), punter Brandon Fields (31), cornerback Brent Grimes (31), wide receiver Greg Jennings (31), defensive end Cameron Wake (33), and long snapper John Denney (36).
Sixty-three of the Dolphins' 89 players, or 71-percent of the roster, are currently 25 or younger.
The Dolphins are going to be relying on a lot of young players this year. Some of those players, like center Mike Pouncey (25), defensive end Olivier Vernon (24), and running back Lamar Miller (24), seem set as rising stars in the league. Others are players who have to prove themselves this season, including guard Dallas Thomas (25), kicker Caleb Sturgis (25), Jamar Taylor (24), and guard Billy Turner (23).
