That's not really accurate. No grreat , elite QB has ever won a SB without a very good team behind him, but there have been quite a few teams that have won SB with just OK QBs.
Prime example is this yrs Eagles, I don't think that Hurts is an elite QB. I think he's a good QB, but the Eagles team is very good
I've always been in favor of building the TEAM 1st because if you have a very good team then you CAN win a SB without the elite QB. But you can't win a SB with just an elite QB
Build the best , fastest race car and who drives is not as important to winning the race
