Okay, I'll answer this a little more seriously. Please take in to account that it
only concerns 'sports' in general, and is just my opinion.
A 'Dynasty' is a team/organization that is consistently winning championships.
A 'three-peat' definetly qualifies. It gets a little touchy (for some reason or another

), when there is a break in the cycle. That being said, if those ******* Pats
managed to win it all next year, that would be 4 out of 6 years, and (in my opinon)
would then have to be considered the best in the history of the Super Bowl.
Uugh, that hurts to say that.
The 'Dynasty' term usually is referred to the players themselves, but in the example of the Pats, if they significantly changed their roster next year and still won it all, then (again my opinon) the organization itself (owner,coaches,GM) would be a 'Dynasty'.
