Unless you're claiming it happens every single game, you're applying the wrong number.
Or are you backing your claim down to "100% of content on TV has some faked element in some episode eventually"? Because that's not a very useful claim.
TV is entertainment, and any faith in the images coming from it is undeserved. Is 100% hyperbole, yes, of course. Is the majority of content on TV fake and over produced, yes, of course it is. It used to be that the label news meant something, but the definitions have been blurred so that opinion shows are now touted as news. After the news label, anything else appearing on the boobtube is meant for entertainment. Believing that the "unscripted" "reality" programming is real is farsical to me. I've worked in production for so long that maybe I'm jaded, but I've worked for religious programming, sports programming, drama/comedy production, live interviews, etc. Everything is touched up in some form or fashion. Education channels exist, but depending on what camp you're in, even those are faking/pushing agendas.
I've never watched the NBA, so I'd have no idea.

Just so you're aware, there are numbers between 0% and 100%.
