I mean not to defend wnelson when he can do it himself, but it's kind of hard to demand proof of what would of happened in a counter-factual.
Having another 17-7 player that turns a bench warmer into a productive rotation player is probably good for tipping the scales in a number of our close losses. Or stopping the bleeding in games we led and then let get away. Probably help keep Davis and Cousins minute load better under control. And yeah, maybe if Cousins wasn't averaging 40 minutes over the last dozen games or so, he might not of had an achilles tear.
