Honestly, I can't blame him for losing his head.
You can tell he told his team to watch for the Pistons to lob it near the basket. He's a film junkie; if there's any coach that knows that play is coming it's Spo. When they know it's coming, it happens, and they offer little resistance in stopping it, that shyt will cause any half decent coach to lose their shyt. I'd do something stupid in that moment too because I HATE when pro teams can't follow simple instructions like that.
