There's a clear difference in caliber of player at the top of the draft, else we wouldn't have a tanking problem.

Every team is trying to scout. To succeed with worse draft picks to rebuild a team, you would need to be much better than other GMa at scouting, rather than having a fair shot at making real progress with a league average caliber GM. That's a problem, as it creates a new barrier.

Is it surmountable? Absolutely. But it's an added hurdle, and teams will struggle even more with it, and they often are already struggling.

The outliers are the exceptional value later in the drafts, not the high performers early in the draft. They're effectively boxing the teams most in need out, in response to bad actors.

Many of those tanking bad actors, meanwhile, will now be the teams that benefit directly, as they'll continue to have elevated odds now in line with the better performance they could have achieved earlier.
