Maybe if you look at "this player puts up numbers but his team doesn't win" you could find examples for practically everyone in the league, but that's not what this is. Embiid and Simmons, every good player on a losing team, they're not better if you camp their ass on the bench and give their usage to some other player. Bagley and the rest of these players do; they make you demonstrably worse on a minute-by-minute basis consistently, where you're better off stripping their usage because they're inefficient, or their defense is so bad that it offsets their offensive contributions and turn into a net negative player.
If all styles are created equal and come down to preference which is what you appear to be saying, why is the league phasing out the face-up, post-up big in Bagley's mold? By all means, John Collins puts up great numbers and he's efficient. He's what people here think Bagley is. Atlanta should be tripping all over themselves going to the bank to max him out. But they passed on extending him. It's not enough to have numbers, if you're an offensive big man in today's game, you have to be more than elite, you have to be a freak.
This team isn't making the playoffs with this core.
