Arrington had harsh words for both in an interview published in The Washington Time s.
"I called Joe Gibbs a coward for leaving," Arrington said in the interview. "You came in, you made some money for your NASCAR team. No one else is going to say that. I'm sure more people thought I was a [jerk] for saying that. Joe wouldn't call me because he knows."
Gibbs retired for a second time from the Redskins in January.
Arrington left the Redskins in February 2006 after injuries slowed him. He signed with the New York Giants and played two months there before a ruptured Achilles tendon in October ended his career.
In 2007, he was involved in a serious motorcycle accident but survived.
He said he has a strained relationship with Snyder.
"I think Dan Snyder is scared to death of me," Arrington said. "He won't look at me. I tried to shake his hand at [a] luncheon. He shook my hand and was like, 'How you doing, LaVar?' and kept moving. I'm probably the only person that's ever stood up to him and never backed down."
49ers: : Offensive coordinator Mike Martz revealed why he called a running play for the fullback on the final play of the team's 29-24 loss to the Cardinals on Monday night: He mistakenly thought the play began at the half-yard line. "We did not know the ball was going to be on the 3 1/2 , obviously, or we would have never called that play," Martz said of the hectic and confusing final seconds of the defeat. That confusion apparently lasted into yesterday. The final play, on which Michael Robinson was held to a 1-yard gain, began at the 2 1/2 -yard line, not the 3 1/2 . The 49ers lost yardage when officials reviewed Frank Gore's second-down run, the second-to-last play of the game. Officials originally marked Gore down at the 1 1/2 .
Steelers: : Running back Willie Parker will return to practice, and coach Mike Tomlin is optimistic Parker will play Sunday against the Chargers. Parker has played once since spraining his knee Sept. 21 against the Eagles, in a victory over the Redskins on Nov. 3 in which he dislocated his shoulder. Also, quarterback Ben Roethlisberger, who has been bothered by an injured throwing shoulder, is likely to practice this week, Tomlin said.
Patriots: : Tom Brady was back with his teammates, laughing and talking with them - and, more importantly, rehabilitating the injured left knee that ended the star quarterback's season in the very first quarter.
More Patriots: : The NFL rescinded a $20,000 fine levied against wide receiver Randy Moss for his comments about officiating. Moss' remarks came after New England lost, 18-15, at Indianapolis on Nov. 2. The fine was never announced by the league.
Et cetera: : The Broncos signed free-agent running back Tatum Bell to his second stint with the team. The Lions released him Sept. 2. ... Five-time Pro Bowl cornerback Ty Law passed his physical and practiced with the Jets after signing a one-year deal.
