I live in Boulder and there is a serious Jets bar here. It's called The Lazy Dog on Pearl Street and there are always double digit Jets fans there on Sundays. If you just want a good sports bar closer to Denver, go to Chopper's near Cherry Creek - I think it's on S. Madison - they show all the games and it's a nice sports bar.
I get the ticket, but I heard Lazy Dog is good. Most sports bars obviously will get all the games, so you can always catch the Jets one way or the other.
I'm not sure if Jets fans still go, but there is a place called the Pour House at 1435 Market St (downtown) that has a rooftop deck (with heaters when its cold). The Jets fans are on the roof. It's not the greatest place to watch a game but it was nice to be in a bar and actually get the sound of the game. The first time I went there i was a little late couldn't find the place and then I heard J-E-T-S JETS! JETS! JETS! coming from up above and I knew I was getting close. HOWEVER, I just looked it up online and some comments about the place said it was the #1 Red Sox bar in town, yuck!! Hopefully they aren't on TV at the same time. There are tons of great sports bars in Denver but most won't have the volume turned up on the Jets game, there aren't too many of us in this town. I had to go to the AFC Championship game by myself the year they played here. As pender30 said, the Lazy Dog in Boulder is known for having Jets fans but that is too far for me to go to have beer in the morning. Personally, i usually walk over to the closest bar with the game on which for me is a dive with no food called Barry's, it's on 1st and Broadway. There usually isn't too many people for the early game there and I can usually get the volume on. It's not a sports bar though really so it's not the coolest place to watch the game, but I can stumble home if I have too many. If you find anywhere else to go, please post. I would like to find a new place to watch our team. There's a place called Andrew's on 11th and Lincoln that is huge and has different rooms for different games but the last time I was there I couldn't find a single TV with the Jets on. I think with Bret Favre we'll get some more air time though. Like I said, there are tons of cool sports bars so it may depend on what side of town you live on. Sorry for the long post with no good answer.
