Dynasty to me means you win with different players. If a King rules for 50 years, he is not a dynasty, but if he passes the rule to his son, grandson, etc, then he is.Lakers of the 80's had Magic, Kareem, and Cooper for the whole run, but MacAddo, Wilkes, and Nixon gave way to Worthy, Scott, and AC Green.Celtics had Russell for their run in the 60's, but Aurbach retired as coach, and Cousy gave way to Havlicek and some other guys changed too.49ers went from Montana and Walsh to Young and Siefert.So the Bills were a very good, very consistent team, but nowhere near a dynasty.
