Disaster of a take. It's not even close anymore
Drew Brees' season and records paired with the prospect of Tom retiring seems to have revived the debate. If you're looking purely are postseason numbers there is no debate. But those aren't the only numbers being used.
For QBs stats like total yards, total completions, career completion percentage, passing TDs, and QBR combine to give a picture of individual performance and effectiveness. Brees beats Brady in every one of those metrics. In the first 4 of those stats Drew Brees is #1 all time and in QBR he's 3rd behind Rodgers and Wilson.
The stats Brady beats Brees in are the ones oriented around team performance more than individual performance. If you're evaluating the greatest QB of all time which stats do you use? The ones more reflective of the QBs influence on the outcome of the games rather than the other 52 guys' influence on the outcome of the games? That's the debate and that's why there is apparently dispute.
Honestly, I think Manning was better than both of them, but I'm not the one debating. It's just my opinion that if you let Peyton, Drew, and Tom play their entire careers in NE with all other things being equal I think Peyton end up with better stats than all of them. But that's an opinion and probably why it's not said much by talking heads.
The empirical data suggests Brees has been a better QB over his career to those who value the individual stats over team stats in their evaluation. That's why the debate seems to have resurfaced.
