In what world is JJJ better than Deandre Ayton, or is this just the basketball version of your Kyler Murray argument?
How they are connected is this:
I truly feel the NFL & the NBA have made transitions over the past half decade. Rule changes in both sports have favored offenses, mitigated injury risks, and almost hamstrung defenses from being truly dominant for long periods of time.
With that being said,
the NBA has very little proof that a dominant low post center can truly reach a level of dominance as has been shown in the past. the game is faster, more well spaced, and more focused on the 3 point line than ever before.
Because of this, if your 5 cant defend a pick and roll, while also collapsing into the paint to help defend during rotations, your entire plan will be ruined as coaches scheme their offenses to defeat you.
If Ayton doesn't become a MUCH better defender, we will be at an instant disadvantage on defense that will be hard to overcome in a motion offense that favors 3 pointers over mid-range jumpers and post play. Which is all we can expect from DA right now.
All of this will not change no matter how efficient he is on offense.
As far as the NFL.... I have said it over and over. The game is changing everywhere..... the question is, how fast will you change with it.
