was recruited by both Network Ten and the now defunct AFL-dedicated Fox Footy pay television channel. He provided special comments during match broadcasts, and was a member of Fox Footy's On the Couch with Gerard Healy and Mike Sheahan from 2002 until 2008. He then switched to the One HD Monday night program with Stephen Quartermain to co-host the new football discussion show One Week at a Time. He also commentated for radio station 3AW. In 2005, Walls was involved in a feud with Sydney Swans coach Paul Roos, after Walls stated that "the Swans can't possibly win the AFL Premiership with Paul Roos' style of coaching". Walls was on the Network 10 commentary team with Stephen Quartermain and Tim Lane when the Swans suffered a 43-point defeat against at Marvel Stadium, after which they were particularly scathing and critical of Sydney's misbehaviour and overall performance in that match. Current coach Matthew Nicks was one of the players singled out, and he was dropped following the match; he never played again as he retired before the end of the season due to injury. This proved to be the turning point in Sydney's season, and ultimately they went on to win the flag (reversing a loss to the Saints in the preliminary final en route) after which Roos refused to accept Walls' apology. Although no longer a television commentator, Walls continued as the "Special Comments Man" for Sports radio station SEN as well as appearing on its Crunch Time Saturday AFL preview program alongside Anthony Hudson, Dermott Brereton and Herald Sun journalist Mark Robinson for two years before retiring. Between 1999 and 2011 he was a commentator for rival radio station 3AW. He has now come out of retirement, providing special comments on matches for Crocmedia. In 2018, he infamously tipped West Coast to win the "wooden spoon", despite still having many quality players. The Eagles would then go on to be 2nd on the ladder and managed to win the Grand Final. Honours In 2006, Walls was inducted into the Australian Football Hall of Fame. His wife Erin, suffering from lung cancer, attended the dinner in one of her last public appearances before passing away on 9 July 2006. With Erin, Walls had three children: Rebecca, Daniel and David. David went on to represent in the South Australian National Football League (SANFL), but his career was affected by three knee
