I have to agree with you that coming into the NBA straight out of high school is a heavy burden for a young guy to handle and if he had the leadership of a mentor like Duncan, Brown’s resume would read differently. Timing, counseling and team composition play a large part in a player's maturity and a teams' fortunes of war in the NBA, case in point being the draft sequence of 1997 where the futures of Boston and San Antonio were dictated. Back in 2001, had Brown gone ahead and attended the University of Florida after signing that letter of intent, who knows where he’d be today. Percentages would probably play out that he’d be in a better place in life than he is now but the road not taken speaks volumes now.
You can't be late until you show up.
