How long should a successful rebuild take?

you think I forgot about Katrina? Come on man. No team or fan base ever went through something that bad. That said, the Saints were on a one year losing season streak going into 06. Broncos are riding a streak of 7 straight.
You posted that the Saints 05 season was the worst in NFL history, UNTIL this years Broncos. A 7 season losing streak doesn't hold a candle to the 1st 40 years in NOLA, much less the effects of the 05 season & the previous 20 years!

The Saints' had 7 winning seasons, 14 losing/even from 1985-2005. 5 playoff appearances & 1 win, with 5 coaches.
Broncos had 14 winning seasons, & 7 losing/even from 1985-2005; 12 playoff appearance & won 2 SuperBowls, with 3 coaches.
I'll gladly trade those records.

Hell the Jets have only 1 winning season out of the last 14 & aren't sniffing another, much less the playoffs.
