Here is more evidence that experience and consistency makes for a better defense.

Texans have been averaging 3 years younger than the top defenses, or Texans at 24-25 yrs old and top defenses, even rest of league average around 28 years old.
Our defense has ranked near the bottom since 2006.
I think maybe this implies we are giving up on young players too quickly? and letting some experienced guys go as FA just when about to get better?
