As good as Lebron was in High School. He still fell short of Jerry Lucas's exploits in High School. and so far the Pro's.
Jerry went to the Ohio High school State Finals 3 Years in a row and NCAA Finals also 3 years in a row. He's was also the 1st to hit the Baqsketball Grand Slam of High Shool Championship, NCAA Championship, Olympic Gold Medal and and NBA Championship. The only two others that have repeated the Grand slam are Quinn Buckner and Magic Johnson.
