I do not think anyone can speculate that college would have not helped Kobe, Gerald or any high school project. Anyone in the right environment will progress. But the ability/talent of Kobe, KG, Howard could have bloosmed faster with college experience, but also shortned their NBA carear. But in this case Gerald is individual proof that college experience what have made a major impact in his progress in the NBA!
Very illogical.
Of course you can speculate that they benefited more from being in the NBA right away. You can speculate either way. The only thing you can't speculate about is them getting paid for their efforts in college. Kobe, Lebron, Amare and Howard might have blossomed slower if they played against weaker college competition first. We'll never know, so it is silly to debate.
Gerald is proof of nothing. The only thing we know for sure is that if he went to college, he would have entered the NBA a year older. We can assume that the extra year would have included some emotional and physical development whether more or less than what would happen in our non-college-attending parallel universe. There are plenty of Harold Miner types that came to NBA with great talent after college but did nothing.
Stop looking for things to blame. The dude is what he is: a mediocre prospect.
"Anyone in the right environment will progress."
Uh, no. Not true. people have limitations and can plateau. Also, even in the ideal environment, some people who can progress will progress slowly and not that far.
