And if you were as good at doing it as you make it sound, you would be working for an NBA team now and not arguing about the merits of prospects on the draft boards.
I am amazed how much people rate their ability to assess talent year in year out. People were smashing Tatum this time last year. Now they are aying player A is a stud adn player B is a bust. Fact is no one here does not have anywhere near the scouting info as much as NBA teams to make that call.
Obviously there is no fool proof way to go about it but it astounds me at the amount of money these people get paid to draft failure after failure. StR had an article showing who the Kings would have drafted if they had just gone with the fans votes on their website and they would have been a playoff team by now if they had done zero homework and just picked whoever the fans voted for each year.
