Brady isn't exactly vital to the success to that team, but he *is* one of the 3-5 best QBs in the NFL right now. I seriously doubt that you can point to more than 4 QBs who have compiled a 63% completion ratio, 197 TDs to only 86 picks, and most importantly, a record of 86-26 since 2001. Oh, and make sure that they've gotten at least 2000 pass attempts over the last 7 years. Good luck!
Two weeks into the season, it's darn near impossible to say who will be in the SB. We can make pretty good guesses as to the playoff teams, though. From the NFC, I'm seeing all of the East except Washington, and the Packers. The South and West are complete tossups. From the AFC, there are a BUNCH of teams that I think could make it. From east to west: Pats, Bills, Steelers, Colts, Titans, Broncos, and Chargers are all teams that I'm looking towards come playoff time, but there are a few that could make some noise (Jets, Ravens, Jags, Texans) come playoff time.
