I live in Boston, and even I can understand how people hate the Pats, because:
1. their dominance
2. the shady tactics (some might call it cheating) of Bill Belichick
3. Tom Brady - how can you not be jealous of him, he can get more chicks than any other guy on the planet. and obviously has had some very good luck on the field.
4. they are hyped to hell, but there were a lot of close calls and some luck involved in their past successes.
