Ramon Sessions declined his one-year, $4.55 million option with the Los Angeles Lakers in 2012 that would have kept him with the team.
Sessions might have remained the Lakers' starting point guard with a deal for Steve Nash seeming less likely.
"I think about it at times," Sessions said Saturday. "It's one of those things that when I opted out, I wasn't expecting to leave. I was expecting to work something out. But you know how the NBA business is.
"A few weeks later, they end up signing Steve Nash. He was a great player, a Hall of Fame player. That's what they wanted."
Sessions signed a two-year, $10 million deal with the Charlotte Bobcats.
