Not really sure what you're arguing at this point - so you're saying that Arkansas is clearly worse without Boogie, correct?
They just won without him. You keep focusing on how bad they were offensively, ok cool - they still won the game, correct? They played their worst offensive game of the season and still won. Maybe they're better defensively now without Boogie? Maybe they're about to get more stops defensively than with Boogie.
Point being, they don't HAVE to have his 15 ppg, especially if they're going to be better defensively. They don't HAVE to get Boogie's 15 pts as long as they get a few more from Adou, a few more from DJ, Knox, Brazille, etc.
I hope they're worse without him. But it's no guarantee, that's my point. UK was better without BJ Boston, UK was better without Sahvir, etc. Like you said, all kinds of examples of this in sports.
And no, I don't think I'm some kind of revolutionary coach who's the first to think of this, but apparently you hadn't thought of it so it seemed relevant to point out
