The undesirable but most likely reality.

In today’s NFL, I still think it is possible to turn the Saints fortunes around totally in only a couple of years, but it would mean having a front office and coaching staff in place that know how to build a new culture of success and new roster foundation that is fit to win in today’s NFL.

In contrast Mickey and Dennis Allen are literally just trying to hang on/tread water in hopes of a miracle saving them. That strategy is what results in a permanent rebuild.
Actually, that’s the norm.
I’ve lost count of how many teams I thought would be terrible forever only to turn it around in one to two years.
