So why is it that the top NBA players never were in college?
74% of the All NBA players last year had college or international experience before entering the NBA. The vast majority of the top players, and players in general, did have experience other than HS before entering the NBA.
If we also look at last years All Stars (excluding those on the All NBA team who we've already accounted for) 93% had post HS experience before coming to the NBA.
The numbers clearly show that the vast majority of players will benefit from not jumping straight to the NBA, their are exceptions of course, but they are rare.
Also you can't tell me the level of play in the NBA is worse than it was 20 years ago that is just a bunch of ********.
I didn't make that argument, did I? Of course quality of play is better now, we have better training, guys playing from a younger age, vastly more people playing both in the US & internationally, scouting is improving all the time, etc.
However, the 1 (or 2) year rule acts as a protective device for NBA teams. For every LeBron there's a bunch of Sebastin Telfairs who ended up being busts and cost teams a lot of money. Having a player go through either college or a minor league system helps clubs scout them more properly before raining them with gobs of cash and potentially team crippling contracts.
The NBA Rookie salary scale helps a lot in avoiding problems like the NFL has with over paying guys who have never stepped onto the court. However during the HS to the pro days of the 90s/00s teams were making awful picks based on hype and not being able to properly scout players. One could say "Well its those dumb teams fault!" but it also cripples the chance for the fans of that team in that city to ever feel like they're building toward a winner.
I just don't see the downside of the NBDL evolving into a full on AAA type system. Maybe each team could be granted some sort of exception if they happen to get a special LeBron esque player once a decade. Say he has to go to the NBDL for the first half of the season and then they can call him up.
