So many Spurs fans are delusional and don't realize that the post prime Duncan big 3 era was a one in a million type thing. Not only were those 3 better as they aged than often given credit for, but the chemistry, continuity, IQ, unselfishness and towards the end depth, is not something that can be replicated again to mostly mask the high end talent deficient against other elites. This team has virtually none of that and the elites are more stacked now than most were throughout that era.
Even with all the post prime Duncan big 3 had going for them, as successful as they were, even they only won 1 championship and it was aided, in part, by a key player on their biggest impediment missing the first 2 games of a series and being hobbled thereafter.
