I don't know what you mean by great; but to me Great is GB in 60's, Pitts in 70s. Maybe a third of the starters HOFers; another third perennial pro-bowlers; the other third plus 5 or 6 on the bench part time or almost all-pro; many of whom have played together for 8-10 years. Teamwork and talent so cohesive, good and dominant mindset, their play overcomes [as Tex says] much more than the average amount of luck. Loading and reloading is really really hard, that's why dynasties are special, and it is not just about front office talent, they need luck. And luck even prevented the great teams of Pack in 63 and 64 and of Pitts in 76 and 77 from winning.
Today Great is not only unrealistic; IT IS IMPOSSIBLE!!!!!!!!!!!!!!!!!!!!
The closest a team in Cap era has come to Great is NE in early 2000s [aided by luck of getting Brady in rd 6; but once they paid him reloading has been sporadic] and the Seattle example, 3 consecutive drafts chalked full of really good players including a cheap QB, w/ a blend of good vets. With proper cap management and average drafts over the next 3 years, Seattle could have been dominant for 5-6 years, before having to rely more on luck to reload. Instead Schneider's unbridled aggression has limited his team's dominance to one year [2013]. Schneider tired to force a dynasty with aggression and wrecked it!
Harbaalke had a solid core to compete for a few more years; but unbridled on the field and front office aggression dismantled that team 2-3 years before its time.
To sacrifice being good in future years and be super aggressive to achieve unachievable greatness this year is patently idiotic. And you'll find out as most teams do: after being aggressive and being more "talented" the team isn't even as good in the aggressive year as it was the year before. Controlled and steady wins 99% of any race; but it wins 100% of NFL races.
