I am not a 49ers fan but I think their team is really exciting. They have some of my favourite players in the league, like Patrick Willis. It is pretty easy to be excited for them, and while I think colin kaepernick is the real deal, it will be hard to fulfill expectations.
The other team I really enjoy watching right now are the Seahawks. I really love what they are doing, and they actually remind me a lot of the niners. Promising young QB, tough physical football and a great defense. I expect both these teams to do extremely well.
I have always supported the packers, because that is what my uncle supported, who is the only link to football I have, since I grew up/ live in a country where it is really not popular. They too are in a pretty good place, and I feel they will be as long as they have Aaron Rodgers. My best friend roots for the Jets,.... what a trainwreck. Though honestly I like Rex Ryan, and I really hope the team will do well this year. If Geno Smith does not work out for them, they will find themselves in a world of hurt.
