OK yep they have young players starting, most teams do.
Here are REALLY big contributors / starters that you list will not touch to take a spot from and thier ages are this year
Vonn Miller - 34 will still be here with Cap hit
Poyer - 32
Diggs - 30
Dawkins - 29
Morse - 31
Hyde - 32
Tre 28 - (knee and achilles)
Milano - 28
Taron Johnson - 27
Dane Jackson - 27
DaQuan Jones - 32
Jordan Phillips - 31
Leonard Floyd - 31
So they really are not getting younger they are treading water, as they will continue to be.
Then why is there a thread about it all the time?
