Your post comes more off as a fishing expedition than the first round of a discussion. Commenting on the fans' delusional behavior is simply not going to engender too many non-emotional responses. However, I will do that:
The Hornets clearly appear to be the superior team. The margin of their victories in the 4 they have won are spectacular. Watching the two playoff games, they simply seem faster, sharper, and more skilled; led by the incredible play of their floor general.
So you wonder why Spurs fans would still believe in their team? There is the matter of 4 rings, and having perhaps the best PF in history on their team, as well as spectacular players in Ginobili and Parker, who are also unmatched in their particular skills. We also have Popovich, who has consistently outcoached contender aften contender.
Also, we have watched the Spurs lose ugly before, to the Suns, the Lakers, and Pistons. Yet those teams fell away, and we were still standing. So, it's not irrational to look past what we see on the court and fall back on what has occurred over the course of the last 10 years. We all know that the worst team can beat the best team once, even twice. Look at Boston and Atlanta!
Another thing is that the level of play of the Hornets is unsustainable. As I mentioned in an earlier post, they are playing like a 70 win team that swept us in the regular season, but that's not the case. They aren't the 92 Bulls. Also, the Spurs are missing a lot of open looks--Byron Scott in no genius for double teaming TD and letting career 3-point shooters have open looks! He tried it, it's working, so why change? It's basic strategy, and nothing to hang your hat on.
The Spurs can buy a basket; and of course part of that is the D, but part of it is just we're cold right now. The Hornets are not the 92 Bulls or the 05 Pistons on D; otherwise they would have won 70 games. It should be fairly obvious that the Hornets are on a monster high and the Spurs on a low.
So, given these factors, it's not unreasonable at all for Spurs fans to remain hopeful we can still win the series. We have a track record you see, and .500 hitters eventually fall back to Earth. I am not predicting we win, because I think you guys have "it" this year (and maybe will continue to over the years), but I would be surprised if we don't at least come storming back and make a series of it. Then mental composure and experience will come into play.
I would certainly enjoy watching West and Stoyakavich crack, once that happens; and it would be nice to see CP's iness get taken down a notch. If not us, I'd guess the Lakers would be able to provide that lesson.
