I think the Benson record is severely skewed by the presence of the Bill Walsh/Siefert 49ers. I fully believe that some of those teams had the ability to win the NFC if not the Super Bowl if they would not have had to get past the 49ers. There would have had many NFC West Titles and easier roads in the playoffs if not for the 49ers being a dynasty in their division.
The only real black marks are Ditka and DA. And if DA is gone after this year, it's not a huge thing in the grand scheme of things since it really just delayed the rebuild that was needed after Drew retired for a few years.
I'd give their ownership a solid B. Payton was as A+, Mora was a B+, Ditka F, and Allen D.
