you gave the example of new orleans who didn't accomplish winning the super bowl in a 2-3 year span. it took them a 5 year rebuilding plan to win the super bowl.
This was Sean Payton's 4th season as coach of the Saints. So I guess you're counting Katrina as part of New Orleans' rebuilding plan?
Furthermore, to say that it was even a 4-year "plan" implies that they were only stockpiling cheap, young talent in 2007 and 2008 in preparation for a big run in 2009. That isn't particularly consistent with their signings of Renaldo Wynn in 2007, or Dan Morgan, Aaron Glenn and Lance Schulters in 2008.
