The point is that development isn't linear and is different for every player.
Every draft is different, the quality of the 5th overall pick one year to the next is not the same.
Then you have different development time due to coaching, number of games played (injuries/covid/suspension), quality of teammates, quality of league, and a ton of other things.
So every player is unique and these one to one comparisons are unfair, especially for a player who has played all of 46 games since being drafted.
