Things have changed on both sides, but between Game 3 of the 2013 playoffs and the end of the 2014-15 regular season, the Spurs are 9-2 against the Warriors (regardless of who is coaching that team). One of those 2 losses was the second night of a back-to-back against a Golden State team that hadn't played in 9 days. It's not like the Spurs have struggled to find success against the champs, even in their current iteration.
Who knows what would have happened if the teams had met in the 2015 playoffs. I'm surprised, though, to read so much chatter from Warriorsland that seems to think their club is the only team chock full of guys with championship pedigrees and to wholly discount just how effective the Leonard/Green tandem has been in those match ups.
Yes, the Spurs still have some work to do to tinker with this roster to optimize its flexibility, and absolutely, the Warriors might still end up being the better team at the end of the 2015-16 season. They're damned good. And everyone, including Monte Poole, is en led to his opinions about these teams and their relative strengths. But the rationale advanced in this piece is just a bunch of rah-rah stuff that lacks much relationship to relevant recent history.
