For those that are not old enough to remember the 70's- there were two teams that for several years defined PUTRID. Houston Oilers and NO Saints. The Saints kept losing but the Oilers got Bum Phillips and became contenders.
The Bears were pretty bad from the late 60's until a couple years after payton came in. As was pointed out, there was no FA, few trades, and the draft was 17 rds for most of that time, I believe. UDFA were truly bad mostly- Drew Pearson was an absolute unique find.
No QB without good receivers or good O line is going to be worth a damn. the Saints had pretty much neither for the whole time Archie was there. Benson never has gotten any better at being an owner, and they really only had the late 80's as a time that they were good. And maybe now- we shall see.
whatever he has done since, Archie played his heart out for 11 seasons in the worst pit in the NFL. Had he gone to any other franchise, he could very well have ended up in the HOF.
