So playing in the nba earlier doesn't actually help players?
not really.. it's a cold thing to say "throw them to the wolves and they'll get tougher" but it rarely works out like that
think of a video game... you read the book for 3 mins and learn the buttons.. then they throw it on the hardest difficulty and say "have at it"
you're not going to START off being better than the guy who read the book for 30 mins and got 3 hours to practice on easy and normal... then plays on hard
these dudes are playing high school learning from scrub high school coaches... then get to college where they play with better people, get better coaching, play better opponents, but they are still learning the basics... high school basics ain't really shyt... they getting used to national travel, press, broads, money (under the table), not to mention the basketball skills
honing that for 3-4 years is going to make you better prepared than 1 year... and that's why you had better ROOKIES.. more well rounded players.. more fundamentals
now if we just comparing age.... 1 guy went straight to the league, his twin went to college... who's the better nba player at the age of 25.... well i don't think that's been looked into as to which breeds better players overall
