I would have to say top 20. These things are very hard to flesh out, however I think for him to turn this team around after Katrina, endure it all after Bountygate and then if he can bring it back atleast one more time, That deserves alot of Credit. I have always been the first to defend Payton with everything he is done, he is a winner through and through, but I also feel like there are Coaches that have overseen whole teams and really maximized results on both sides of the ball alot better than him. To me he is the greatest coach ever, but legacy wise, there are ALOT of amazing coaches through the years
