Obviously a Colts-Pats AFCCG, if it happens, will be huge in that it will decide who goes to the Superbowl. Just like every championship game is. But let's look at just how big this game is in other regards. This game, if it does indeed happen, will decide alot about how history views these teams. Of course both of these teams will have to win their divisional games first.
If the Patriots win, they are the clearcut dynasty of the 2000's. There is no question about it. The Colts greatness over the past several years would become an afterthought as far as how they are judged. No one will ever be able to take away our wonderful championship last year, but there will be no doubt that we would be small potatoes to the Pats. And of course, Brady would be 3-1 against Manning in playoff games, which would be a dominating advantage.
But what if the Colts win, and then go on to win the Superbowl? Suddenly, the Colts are right with the Patriots. You have to look at the Colts in terms of how they rank in all time NFL teams. The Colts would go into next year with the hype of going for a three peat. Manning and Brady would be tied in head to head playoff games (2-2). The Patriots would be three years removed from a championship, which is a long time in terms of sports. Suddenly the 2 teams are pretty close.
So aside from the obvious importance of determining who goes to the Superbowl, there is alot riding on this game if it does indeed happen. If the Pats win, they have a whole lot over the Colts and are the clearcut unchallenged dynasty of the decade. But if the Colts can win and then go on to the Superbowl, the Colts are right there with them. Then you have to look at the 00's as being the years of the "Patriots and Colts."
