I agree 100% on this one. Sadly, discussions inevitably get drawn to issues of the past. I am guilty of it as well.
What eludes me is the rationale behind the at ude of some (clearly not including you) Spurs fans that, right after a Mavericks win over the Spurs ( , even in the same night), any Mavericks fan gives a damn as to how many championships the Spurs have.
It is awesome, truly commendable, how successful the Spurs have been. I say that without sarcasm or agenda. In terms of overall success over the past decade, they have so far outpaced the Mavs, and really the rest of the league, that it's not even funny.
But sports are about the here and now. I'm a fan of two teams in other sports that have won championships recently. But when those teams of mine lose to a rival, I don't feel any consolation in reminding the rivals fans as to how many championships my team has. Because, at that moment, they dont' care--and why would they?
