Wins don't matter much for a QB? Man, you are completely missing the point of the game and the position. It's the QB's job to turn lead into gold.
All first ballot HOFers? Definitely.
Montana the best QB? Na. He was great, yes, but he played on some monster teams with a monster coach. He had it FAR easier than, just for starters, Marino, Elway, or Favre.
Aikman the best QB? Not even the best Dallas QB. Probably the luckiest QB in the history of the NFL. I guess you were joking.
Terry Bradshaw pretending to be a hick? Yes and no. He is a hick, but he knows how to make that work for him. If he were ultra-retarded, he wouldn't still be on TV.
Manning sat out the last game? I didn't know that. Makes his season look better.
Brady is a great QB, but he's never been really ALONE like some have. It has never been solely up to him. He always knows that if he falters, there are dozens of other stout dudes both on and off the field who can pick him up, dust him off, give him time to rest, get a turnover, call a great play for his next series, etc. The 2000s Patriots are the greatest NFL team in history, and they can make a good case for greatest sports dynasty in history. Perhaps ironically, this diminishes Brady's accomplishments, because he has had more help than perhaps any other QB. The impact of Randy Moss on this season CANNOT be overstated! If you think Brady's supporting cast is anything but critically important to these kind of discussions, you have never been out there with the rock in your hand, millions of eyes on you, large angry men running right at you, looking desperately for somebody, please, SOMEBODY to be open so you can convert this 4th-and-long and keep the season alive.
A great QB can win games here and there on talent and desire, and maybe he can even drag his team to the Super Bowl by sheer wilpower, but he can't win the Super Bowl all by himself. If you don't believe me, just ask John Elway. The playoffs are a completely different game from the regular season, and the Super Bowl is a completely different game from the playoffs.
Out of these three seasons, my ranking:
1. Marino (for doing the most with the least)
2. Manning (for just plain crazy stats)
3. Brady (for overall excellence, and it is a shame to rank it 3rd, but there it is)
But none of these three is the greatest QB overall.
