As someone who agrees with that poster I’ll take a stab.
He’s an elite recruiter and has raised NIL at both locations he’s been at. His teams play hard every possession which includes an emphasis on rebounding(novel) concept. His teams push the pace and rely entirely on shots at the rim or 3’s.
He’s not stuck to one defense and will mix man or zone depending on matchups. Teams struggle to score inside against his teams as they do a great job cutting off dribble penetration and are very physical on the ball. The only negative is he hasn’t done this at a power conference level, but it’s the same system Oats runs with what I would argue more emphasis on defense.
