I've been a Colts fan since 2006. I was in between teams before then from the Giants, Jags, Eagles and a few others. Most people that don't live in the U.S and don't follow the NFL much jump on the patriots bandwagon, mostly because they play Madden and want to be the best team which is the pats in pretty much every game besides maybe 07.
Good, young teams to go for would be-
Jets- A franchise QB in their rookie year, head coach is a defensive guru, decent running game.
Texans- Young team, top WR's and RB's, improving defense.
Bears - finally sticking with a frnachise QB, great defense, good running back.
Broncos- have suprised everyone this year, undefeated, their best defense in a decade, good coach, good, young WR's and RB's.
Ravens - Young QB, best defense in the league
