You are shifting your argument. Every team in the league has the first three rounds to draft from every year unless they trade out. The claim you erroneously have emphasized is that a team must pick high for multiple years before it can accumulate enough talent to build a winning team. As I've said, if that was true teams like the Jete would be perennial division winners. Also as I've pointed out, it's not how high you're drafting, it's how SMART you're drafting.
You make no sense. The 2001 Patriots won on coaching, special teams and defense with an offense ranked 19th overall in yards gained, led by a sixth-round QB starting for the first time. In fact, talent-wise the Pats arguably had the weakest group of skill-position players among all playoff teams that year. The Rams were "stacked," not New England. Talent didn't win the Lombardi that year, a team used to scratching and clawing did.
