Crawford did not hesitate when asked if he had any regrets. There are two, he said. The first is regarding his actions that led to a guilty plea of falsely stating income in 1998 after an I.R.S. investigation into several referees’ pocketing cash from downgraded airline tickets. The second is an incident in 2007 in which Crawford and the San Antonio Spurs star Tim Duncan had an on-court verbal altercation. Duncan said Crawford challenged him to a fight. The tax thing, I was petrified, to be honest with you. It was the worst. If they wanted to scare you, they did. If that’s what they wanted to do, they did. They did it. I was so grateful to get the chance to come back. The Duncan thing probably changed my life. It was just — you come to the realization that maybe the way you’ve been doing things is not the proper way and you have to regroup, not only on the court but off the court. I had seen a sports psychologist before that. But after, I saw him a lot more. His name is Joel Fish. He’s worked with a lot of athletes. It gave me a new perspective.
