Both have only won a single SB but Payton's offensive schemes & play calling are much better than McCarthy's. Drew Brees is a good QB but not in the same class as Rodgers. I believe if Payton & Rodgers had been paired together it would have been more than one SB. So does you question imply that McCarthy is just as good a coach as Payton?
This may be so - we'll never know unless we gain access to the multiverse - but I did read recently that Payton wanted a QB who did not "wing it" like say Fields and Russell Wilson, so he probably would've like all of Rodgers's complicated play calling. "If this, then this. If I nod with my LEFT eyebrow, I want the X reciever to go LEFT, not right, and the Y guy to go straight, not out. And if I wiggle my ass twice - not three times, twice - it means the running back needs to stay in and block, and the tight end must release immediately, but not over the middle. Never over the middle."
"The Devine era is actually worse than you remember if you go back and look at it."
