N/S... What 2 teams make the biggest surprise???

What two teams (one in the NFC - one in the AFC) besides the Saints do you think will be the biggest surprises in 2012. Remember: surprise mean not expected (don't say Patriots and Giants).

For me:

AFC:
Tennessee Titans - I think their offense is extremely potent and Munchack has had a full year to emplement depth and power into this offense. Let's start with Jake Locker. He is a stud prospect whom I believe will make peoples' jaws drop this year. Remember what he did to us last year. He is going to be very special. Chris johnson is healthy and ready to make up for lost time. I'd be very surprised if he doesn't at least get 1,400 yards this season, and they are very deep behind him with power and speed. Their WRs are exciting - Kendall Wright is going to be special and he and Locker have already built a relationship. If you add Nate Washington and Kenny Britt to that mix - they are lethal. I love their O-line - Stewart and Roos are the best tackle tandem in the league and are extremely underrated. On defense, they have the best young group of LBers in the league. I'm not in love with their secondary, but their D-line is very solid. I predict an 11 - 5 record for them this year. At worst, I think they win 9 games.

NFC:
I know they're being talked about some but the Bears are primed to win a lot of games this year if that defense and Cutler can stay healthy. I love Forte and Bush. They can really make that running game come to life. Forte is special. Cutler is one of the better QBs in the game, IMO, and with this group of WRs, this offense can be lethal. The O-Line still has question marks, but they are talented. Defensively, that group of DEs is freakin' awesome. Any team in the league would and should be jealous. They have good LBers that could be great if Urlacher stays healthy. They have solid secondary play (I don't love their safties). I think they could easily win 10 games... If they can upset Green Bay and Detroit once each, they could have 12 wins.
