For me, Chris Paul had the talent and IQ to be the greatest point guard of all time. Unfortunately he did not have the personality to match.
In my opinion, Paul was never a real leader on any teams he played for, he was more of a dictator. Paul always thought he was smarter than everyone (including his coaches) and when his teams failed in the playoffs, it was never his fault.
This is why I have CP3 behind John Stockton in the all time point guard rankings. Stockton did what was best for his team, not his individual statistics. Stockton actually took pay cuts to keep guys on his team, Chris Paul would never fathom doing something like that.
