Atkinson set the Raiders' single-game record for punt return yardage in 1968, with 205 yards against Buffalo. He ranks fifth on the Raiders all-time interception list with 30.
In a regular-season game in 1976 vs. the Pittsburgh Steelers, the Raiders' arch-rival, Atkinson hit an unsuspecting Lynn Swann in the back of the head with a forearm smash, even though the ball had not been thrown to Swann. The hit rendered Swann unconscious with a concussion. Atkinson had also hit Swann in a similar manner in the previous season's AFC Championship game, which also gave Swann a concussion. After the second incident, Steelers' coach Chuck Noll referred to Atkinson as part of the "criminal element" in football. Atkinson subsequently filed a $2 million defamation lawsuit against Noll and the Steelers, which Atkinson lost.
Atkinson currently works as a Raiders broadcaster, doing the pre-game and post-game shows. He also hosts a television program called Behind the Shield. Since 2008, Atkinson has been a major spokesperson for "The Clothing Broker", a warehouse-style clothing store in Oakland, California. He also appears regularly on NFL Network "Top 10" shows that involve the Raiders, providing insight and his perspective on the many "controversial" calls made against the Oakland Raiders. Some examples are: 1) Perhaps the most controversial call - the Immaculate Reception - Atkinson contends that it was a dead ball because of the "double touch" rule, and because Raider's linebacker, Phil Villapiano, was "clipped". 2) Atkinson points out that the Tuck Rule had never been used until it was used against the Raiders in the 2001 AFC divisional playoff game and never used again (the Tuck Rule was abolished on March 20, 2013).
