With so much new talent on the defense acquired through the draft, the experience of the players will obviously be limited.
With rookies Chandler Jones and Dont'a Hightower both expected to start and Tavon Wilson and Jake Bequette expected to contribute, second year players Ras-I Dowling and Sterling Moore projected to either start or play heavy snaps and third year defenders Devin McCourty, Brandon Spikes and Kyle Love all returning starters, there really isn't much experience on the Pats defense.
Jerod Mayo and Patrick Chung are 26 and 24 respectively and are considered veterans in comparison to their other defensive teammates. Other contributors like Kyle Arrington, Jermaine Cunningham and Ron Brace are all under the age of 25.
As we've seen over the past few years, talent can only take you so far in the NFL and young players tend to make many mental errors. Whether it's overshooting a gap or taking a bad angle to the ball, you have to take the good and the bad with the younger players.
Bill Belichick has so often preferred veterans on his defenses, so he can run his complex read and react systems. However, long gone are the Tedy Bruschis, Mike Vrabels and Rodney Harrisons and in are the new guys.
There's no doubt New England has a lot of talent on its defense; getting them all to play together and consistently will be the challenge.
