But it wasn't the best option available until the league mandated a ridiculous 1 year rule to protect the owners from themselves (when in reality they didn't need to do that as by and large the straight from high school players had more success than the ones that went to college and there were very few total busts).
Does your list of "successful" players include those who didn't get drafted high, or didn't get drafted at all? I think those kids lost their college eligibility when they entered those drafts, and that was one of the reasons for the one and done rule.
If they went undrafted as long as they didn't sign with an agent they were college eligible. In fact, the only two players I found that declared out of high school and were not drafted were Charlie Villanueva (he might have withdrawn, I've seen conflicting reports) and Thomas Hamilton, both of whom ended up in college after the draft (Charlie V obviously had a pretty career after 2 years at UConn, Hamilton went to Pitt and played 33 games in the league including 11 with Boston).
There were a number of 2nd round picks, though Stephen Jackson, Amir Johnson, Andray Blatche, and many others had or have long NBA careers (and a guy like Blatche with all the off court problems, probably would not have had he gone to college). This notion that the NBA was protecting the kids from making a terrible decision is just nonsense. The rule was changed to protect the owners from themselves.
Two things:
one, *college* players who didn't hire an agent could retain their eligibility. High schoolers who declared for the draft lost their college eligibility, at least they used to. The owners aren't overly altruistic, but aside from looking out for their self interests, this was one of the (fairly well known) reasons for the one and done rule.
two, you seem to be looking at players who went directly from HS to the nba. There were a number of HS players who declared for the draft, weren't drafted, and never played in the nba. They don't show up in your analysis, and I don't think they'd fit into the "successful" category.
One. I named two high school kids that declared for the draft, were not drafted, and went to college. So I'm not sure where you are getting your analysis that they couldn't go to college.
Obviously I never said they couldn't go to college, just that they weren't eligible to play D1 college ball. You listed a player who never hired an agent and withdrew from the draft before it occurred and a player who attended college but, according to his wiki page, never played ball there. I'm "getting my analysis" from having followed the nba and the draft when these things were happening. Here's an article about one of the players:
http://bleacherreport.com/articles/2100489-lost-and-found-taj-mcdavid-today-is-more-than-an-nba-draft-punch-line"According to NCAA rules, high school students who applied for the draft surrendered their eligibility to play for an NCAA member institution."
Look into the subject and you''ll see the same thing elsewhere.
EDIT: Two. I've seen the list (it includes Villanueva and Hamilton). Tony Key (who didn't qualify for college which is why he declared before playing Juco ball). Taj McDavid (who wasn't even a high school All American and ended up at a DII school). DeAngelo Collins (who was a disaster off the court and wasn't drafted because of it). Lenny Cooke (who was too old to even play as a senior in high school). and last but not least Jackie Butler (who went undrafted, but ended up on the Knicks roster after the draft before signing a 7 million dollar free agent contract with the Spurs).
So you basically have a bunch of guys that had to declare for personal reasons, that had no business declaring, or that ended up back in college (whether DI, DII, or Juco).
I didn't check much but the list I saw also included Ellis Richardson. As you've noticed, those players weren't exactly success stories. Also, when you're considering whether the players who went straight from high school to the pros were successful or a bust, consider that many of the guys who were drafted late thought that they were going to be high lottery picks when they declared. A year or two of college would have definitely helped those players out.
The rule wasn't about protecting the players, it was about protecting the Owner's from themselves.
In general it was about both. They added the process to do the early entry exploratory process at the same time they added the one and done rule (iirc).
Even with that, I wouldn't characterize the rule as "protecting owners from themselves". They were getting players in the draft that weren't nba ready and hadn't played much against high level competition.
