This doesn't really speak against my argument. I'm not arguing that a player, regardless of skill or longevity, will consume all of the available FTA's in a game if he's not playing alongside a superstar. I'm saying that Kyrie Irving cannot get to the line 9 times since there are a finite number of free throws to be taken, and that number is shared by 2 other superstars as well as the other players on the team.
FWIW, Irving averaged more free throws per game than Butler in his first three years; without any superstars. In his first year with LeBron, he was getting nearly a 30% FTr, then it falls off a cliff. By comparison, Jimmy Butler is getting to the line 54% of the time this past season... No, I don't think that would hold true playing alongside two other superstar players.
