I'm excited that we're winning, just that I'm not ready to crown them champions just yet as some are ready to. I want to see us beat SAS(at full strength), Chicago, Cleveland, Portland, Clippers, etc... We all knew this team was good, but is it great?
Who is crowning us as champions?

I can tell you right now. We are going to beat many of those teams this season....and we are going to get beat by many of those teams this season. Look around the league. Last year, a team with the world's best PG, PF, and a DPOY candidate at center led by a championship-caliber coach (allegedly) barely got out of the first round and then fell short in the second.
OKC, sporting the 2nd best player in the world, the 2nd best PG (some say best), another DPOY candidate, and some quality players around them couldn't get to the finals.
Portland--same. Portland is a very good team (despite what people want to think) and they snuck into the 2nd round only to get trounced by SA.
Look at GS. They are very good. Are they "serious contenders"? Probably not in most people's eyes; yet, they will make the playoffs and they could very well get to the finals from there. It's anyone's game right now.
Are the Rockets great? That's the kind of thing that gets determined in hindsight. there have been tons of "great" teams that have accomplished nothing (at least in the eyes of the most demanding fans). I suppose Reggie Miller's career in Indiana was a failure? Malone? Barkley? People draw different lines in the sand and some of those lines are, frankly, ridiculous. You may as well demand your children become president of the United States--ALL OF THEM--otherwise, they are failures.
Like you said, this team is good. Let's all sit back, relax, and enjoy that. We all seem to agree that Houston is going to win between 50-58 games....which means we all agree that Houston is going to lose 24-32 games this season. So what's the big deal? We'll beat the pants off of some good teams and they will do the same to us--what does that tell you? We were 4-0 against SA last year--what did that net us?
Don't forget what Morey said, this team will be better at the end of the season (pre-playoffs) than it is now. I mean, Cleveland just lost to the Knicks--THE KNICKS!. Should they panic?
Speaking for everyone--I'd say we expect to have a solid season, make the playoffs, and then anyone who isn't nervous about the playoffs is delusional. All 8 teams will be nervous about the playoffs in the West. San Antonio had to go through Dallas, Portland, and then OKC to make the finals where they then had to beat the Miami Heat. Does that sound easy?
I guess I'm just confused about what it would take to make it more comfortable for people. Would Rondo guarantee us anything? Would Rondo+Millsap guarantee us anything? No. That's why it's fun. Because we don't know. I guarantee if we had those guys people would be worried about Rondo's shooting and Millsap's defense and how Harden and Rondo co-exist because they're both ball dominant and we have no depth (because we traded it all for those guys)--and on and on.
