Yeah, nobody is saying that Ayton is Jokic, Embiid, Davis, Towns, etc., but despite what various catch all metrics indicate, he's not Poeltl either.
He's much more versatile (vertical spacer, who can post switches, with a passable and improving jumper and switch ability), is only going on 24 and has already proven he's matchup proof in the playoffs.
For an organization that refuses to bottom out and can't attract stars in free agency (Aldridge was for family reasons + the chance to play for a perennial contender), this is a rare opportunity and one that shouldn't be passed up because he wants a % of the cap (25 as opposed to 20ish) which is negligible in roster building.
