I kind of like games and series against the Clinkers, for their being competitive but never personal. The Suns and Clinkers have never had a history. Their games are the opposite of the uncomfortable games against the Kobe Bryant-era Lakers. Moreover, in various games against the Clinkers going back years but including this one, I have seen suggestions that strategy was emphasized, not any rivalry. Back in the 2006 playoff series against the Clinkers (I guess it was a semifinal after that memorable and ugly series against the Lakers), commentators talked of Mike D'Antoni and Mike Dunleavy "playing chess" against each other, constantly shifting lineups and doing different things to win. I have appreciated that approach. I got sick of personal rivalries and soap operas in basketball years ago. Sports should never be personal. Even were I capable of playing sports competently--I'm not, being mildly disabled--I don't have the mindset to be a professional athlete. Don't care enough about competition.
Granted, for a while, Suns fans were getting annoyed about Patrick Beverley's behavior back circa 2021. Yes, well, Beverley left the Clippers right after that, so there was no chance to develop a history of clashes with him. He doesn't usually stay with one team for very long, either because he's a mercenary or possibly because he annoys his own teammates (as well as opposing players and fans) so that his teams keep getting tired of him.
And granted that this can apply to any number of teams--the Milwaukee Bugs, for instance. AFAIK, there was no animosity in the 2021 Finals, because the Suns and Bugs don't meet often enough to care about each other. The Lew Alcindor coin-flip was over fifty years ago, and probably only obsessive Suns fans still care about the Bugs winning it. Why would I; I wasn't even born yet.
As for the Suns-Spurs rivalry, I never got very upset about those failures either. I tended to say "Awwwww...maybe next year." (Although like everyone else, I was delighted at the 2010 sweep.)
