Banks writes a well-written and well-thought out article, but it has some inaccuracies.
First, he suggests that sooner or later the whole Patriots approach will fail. Perhaps, but the Patriots approach has "probability" on its side. Unlike the Redskins, who basically take wild gambles year after year, hoping to roll craps, the Patriots method is designed to give us the BEST CHANCE at fielding a highly competitive team EVERY YEAR.
No blowing up the team and rebuilding (see Titans, Tennessee). EVERY YEAR. Some years things won't work out, but we won't be in cap hell as a result, we'll cut the players we need to, and move on.
That's the genius of it that he's missing. "Sooner or later this won't work" isn't the point at all. The point is over a greater period of time than ANY OTHER possible system, it WILL work.
