Ummmmm, is that not a Dallas Cowboys site? What team would they predict a dynasty for, GB? PIT? SF? NE?
Things have to fall just right for any team to approach that D status including keeping the band together and staying healthy.
Only one team has approached that in the cap era and SB teams missing the playoffs the next season have become too common. Sustaining anything in the NFL is a tough job.
There will not be another dynasty, I don't even think Belichick would create that if he stayed another 10 years in the game. It is too hard to keep a team together long enough and too hard to build enough depth. The secret to Belichick's building as dynasty wasn't his acquiring stars, he paid more attention to all 53 than anybody else in the game. Belichick's secret was depth, there were no unimportant players, everyone had a role and he constantly reviewed his roster to see where he could upgrade.
If you looked at Belichick's roster, as compared to the Cowboys', what % of the cap do you think you'd see tied up in the starting 25? I'd bet Cowboys would be at the top and the Pats close to the bottom in top heavy cap. The Cowboys hope they don't get injuries, the Pats plan on it.
