to be fair to them, I think there's a difference. While the expectation that this team at this time will win almost every night is fun, for those who "still" don't believe in the team it seems as if the vast majority are saying "show me in the playoffs". Does it matter to most of us if the team goes 55-27 or 60-22 or 65-17 if they lose in the first round? Conversely, I don't hear many people moaning that the 1977 championship team "only" won 49 games.
It actually reminds me a lot of the 2001 Mariners. You never hear people talk about them as the "greatest team of all time", even though no team in history has won more regular-season games than they did. When you lose in the playoffs, you don't get that respect. And it's not as if Portland (again, like those M's) has a track record to build off of and a steady build to greatness (like, say, OKC or the Spurs). Even HOU, with little to nothing remaining since they were last relevant in the McGrady/Yao years, can point to Harden and Howard being big parts of Finals teams very recently. We don't have that--to the outside world, we didn't change any of the Top 4 of a team that won 33 games last year.
So it's not necessarily amazing if people don't hop on (or fall off) the bandwagon after this 4-game trip. It'll be fun to watch, but at least for me, I'm going to go with the Winston Wolfe approach--"let's not start sucking each..."
