Marino started his career with a bounty of good playoff games. He started 27/14 in the playoffs (historically extremely great, would have wrecked every single player as far as TD/INT besides Joe Montana until Kurt Warner showed up and went ham on the world), anyway in his 30s crumbled to 32/24 by the end which paints a drastically different, very confusing light on his career.
I did make one huge, glaring mistake when I tried to make my all time QB rating in that last argument, one that I was reminded of the last couple days. I left out fucking Kurt Warner!!!! With a look to quantity of good results as opposed to the "perfect qb rating", the best QBs in playoff history are like
S tier Montana>Bradshaw>Brady>Warner>Brees>Rodgers
A tier Favre>P. Manning>Young [Better Manning can change that this season, of course]
B tier Elway+Marino>Aikman>Staubach [Marino edge if you prefer best statistical results or completion %, Elway should get the nod if you care about him earning the 1 SB win he really earned and Y/A]
And still, I might be forgetting some 70s or 80s dudes, I am not 100% perfectly studied on the stuff that came before I lived, I threw out anyone I knew sucked though e.g. super suck Joe Namath. Picking the best out of Montana, Bradshaw, Brady, or Warner comes down to what you believe about eras and what you believe is important about playstyle, or even what you believe about their teammates. To put Brees or Rodgers #1, you have to go with the most on paper perfect statistics. & If you want to hype someone from A or B tier over Warner, Brees, or Rodgers then you basically have to care more about outcomes (which are team based) than what statistics really say has happened, which is a whole OTHER argument. It just all piles up, it is a really hard subject to perfectly argue.
Also, the Tom Brady part of this shit is easy as hell to get. He has the 2nd best TD/INT of all time to only Montana. His Y/A is worse than almost everybody else on any of these tiers. He is truly the best master we have seen of not fucking up games, and of continually doing the same good things drive in drive out. The Patriots have made 8 AFC championships in 13 years, mind boggling shit. His drive in drive out consistency is a huge part of things no matter where his talent was when they won Super Bowls (really not matching the hype until the 3rd Super Bowl), they win whatever defense they trot out or whatever offensive style they pick. Of course you have to ask what about the defenses, what about the no wins after the first 3, and how much does BB matter (Madden or BB is the greatest coach of all time, accept no other answer :))
