Roberts was educated at De La Salle College[1] and Melbourne Grammar School[2] and attracted attention after kicking four goals in the last quarter of the 2011 TAC Cup Grand Final to lead the Sandringham Dragons to victory.

Trailing by 33 points in the final quarter, Footscray fought back to snatch the lead, only for the Tigers to steady with a goal and seemingly have the game won.

[6] In 2016, Roberts was not selected until the Round 6 clash against North Melbourne due to recovery from an injury interrupted pre-season,[7] but would then play 15 of the remaining 16 games during the home-and-away season.

Despite suffering an early facial injury, Roberts returned to play arguably his best game for the club, holding the dangerous Jeremy Cameron goalless as the Bulldogs advanced to the Grand Final.

In the match, Roberts combined with Joel Hamling to shut down Sydney's twin threats of Lance Franklin and Kurt Tippett, limiting their output to just one goal to help the Bulldogs clinch an emotional 22-point win, ending their 62-year premiership drought.
