In February 2009, Rioli was selected for the Indigenous All-Stars that played a pre-season match against the Adelaide Football Club. Following his successful debut season and promising start to his second, he was compared to Gary Ablett Jr., who also began his career as a small forward with the potential to become a "dominant, match-winning midfielder". This was due to the "sublime skills" he displays, and his "ability to make something out of nothing with vision and an instinct for the game." Former footballer and journalist Garry Lyon said in an article for The Age, that when Rioli is ready to take on a greater workload in the midfield, will be determined by his physical and aerobic capacity. Rioli's greatest challenge in the coming 12 months being to incorporate the "gut" running into his game that the likes of Ablett, Chris Judd, Lenny Hayes and Brett Kirk have mastered.
Approaching the end of the 2009 season, Rioli bought his first apartment and declared his allegiance to spending his whole career with Hawthorn, he also revealed his intentions to help bring more players down from the Northern Territory; "That's the real goal for me, to get more kids drafted from the Northern Territory." After Hawthorn's demise in 2009, Rioli gave his support to a project which aims to teach Indigenous people in remote areas about the damage drugs and alcohol can do to the brain. An image of him is used in flip charts developed by the Menzies School of Health Research as an example of a person with a healthy brain. Sheree Cairney, the lead researcher at Menzies School, says there is a lack of knowledge in remote communities about how to treat drug and alcohol addiction, with the problem being "very, very widespread." At the end of 2009, he was awarded the AFL Coaches Association award for Best Young Player, covering his first two years in football. He also received the Phil Manassa Medal (Goal of the Year award) for his round seven effort against Essendon, and came second in the Peter Crimmins Medal behind the club's captain Sam Mitchell. When Rioli kicked the goal of the year, commentator Bruce McAvaney described him as a "delicious young footballer" and the description "delicious" has become strongly associated with both Rioli and McAvaney.
