"I think there's a lot to this," said John Momot, a lawyer nearing 40 years of criminal defense in Las Vegas who played himself in the 1995 movie "Casino" and provided expert cable TV commentary during Simpson's monthlong trial in September 2008.

"I don't think O.J. Simpson could ever get a fair trial, period, based on his reputation from California," Momot said. "But based on these allegations, if you took Joe Jones from the street and put him in the same situation, I think it would be possible he'd get a new trial."

Simpson's lawyers also say that while continuing to represent Simpson through oral arguments in a failed 2010 appeal to the Nevada Supreme Court, Galanter kept a lid on his own behind-the-scenes involvement. That nearly extinguished any chance Simpson had to claim ineffective representation in state or federal courts.
