I agree Colts, Pats then everyone else. With the Colts being the second youngest team in the NFL we're going to be around for a while, hopefully the Pats too.
This is an interesting note, and probably deserves its own thread at some point...but Indy is very young on defense. As far as the offensive side goes, NE is a tiny bit younger, actually. Not much, but a bit. It's on the defensive side of the ball that the youth of the Colts shows. I only looked at the starters, which is not exactly scientific--but Indy's starters are about twice as young as our defensive starters.
Now, that is just on the starting roster. We have youthful backups. And we were also younger when Sanders was starting instead of Rodney, e.g. But that does not change the reality, which I think everyone acknowledges (and has acknowledged).
Moreover, you could look at it from a different perpective, and say that our defense is twice as experienced.
As a result of this, youth is not any guarantee of excellence (see Buffalo, Houston, NYJ, and Arizona, all very young teams).
Anyway, no need to hijack the thread; a topic for another time.
