If you're a homer fan who is to bias to be objective, this probably won't be an effective debate for you to partake in.
In my opinion, Brady and Peyton aren't that different in the playoffs and Flacco is a good QB.
First, with Brady and Peyton:
Both are great QBs. But for some reason, everytime Peyton loses in the playoffs he's labeled as a choke, and every time Brady loses, people always take things into context (Well this guy dropped this pass, or that defense couldn't get stops, etc). I get one is 9-12 in the playoffs and the other is 17-7...but those are team records, not solely QB records.
Mannings last 4 one and done's:
Ravens, well they went on to beat the Patriots. Manning through the game losing pick, but at least he put the position in a great chance to win the game in the 4th quarter. Can't say the same about Brady.
Jets, Brady ended up losing to them too. Can argue who played better. Manning had a higher rating and QBR (Brady had an 9.8), take that how you want. Neither played great
Chargers, Brady actually won the game, but Manning played better and scored more points. Volek finished the game to beat the Colts while the Pats beat Rivers who was playing on a torn ACL.
Steelers, Brady didn't play them in the playoffs but he beat them in the regular season. Steelers went on to win the Super Bowl (even if there was some health from the refs). But they were a legitimate team.
Chargers in '08 was bad as they were an 8-8 team.
The early parts of their playoff careers is what will largely define them. I'm not going to say Manning would have won three Super Bowls with the Pats, because that may not be true, but Brady did drop into a better situation. Entire careers are important to judge. Players are most critically judged not by their play when they're first coming into the league or when they're old and on their way out but during their prime years. Brady and Peyton's playoff success during their prime years is largely similar. Manning has thrown a game losing INT in the Super Bowl which is super unclutch. But in last years Super Bowl, Brady had the lead in the fourth quarter and had two drives to win the game. One ended in an INT, the other in a punt (I won't count the desperation drive). Brady has 3 rings to Mannings 1 and that's what you play for. But Super Bowls are team achievements, not just QB. I still like Brady more than Manning, but I wouldn't say he's out of his league.
As with Flacco. I think he's good, I have to admit. For those who haven't seen my other posts, Flacco is my least QB in the league. He's played very well in his last two post seasons. Has he outplayed Brady? Contextually speaking, they play against different defenses, one is pretty good with veteran leadership and the other one is made of swiss cheese. However, if you believe Brady outplayed Manning in the '03 and '04 playoffs, then you have to argue Flacco outplayed Brady. If Flacco plays well Sun (win or lose) then I think he deserves a spot in the same tier of QBs as Eli Manning and Big Ben. IMO. He's inconsistent, but he makes up for that by coming up big in big moments.
Tier 1: Brady, Brees, Rodgers, P. Manning
Tier 2: Big Ben, Eli
I'm open to hearing counter arguments! But please, be as objective as you can. I'm sure I'll get bashed by some people but whatever. I'm willing to change my stances if I hear valid arguments. I'm not the type of person that ignores arguments that prove me wrong.
Also, before people starting sarcastically saying, "Yeah, let's totally trade Brady for Alex Smith". I never said Brady sucks, I said he's a top 3 QB. Just saying he doesn't play significantly better than Manning in the playoffs.
