How can people doubt the patriots not making it all the way?

Winning 16 games will just put more pressure on you to win the playoffs.How great have the Patriots looked the last 2 weeks?Manning may have taken 6 years to do it so now he knows it can be done.What happens if Brady gets knocked out of a game?Are you sure that your backup can do the job?That is why they play these games.the best team does not always win sometimes it is the least injured.I think the Patriots are a great team but just want to point out there have been upsets before.
