[8] He first represented Richmond in a pre-season match against Fremantle in his home state, playing a dual role as a general and rebounding defender.

[14] In the month following his side's 2017 premiership win, Broad was embroiled in scandal for distributing a photograph of a nude woman without consent, the result of which saw him suspended for the first three matches of the 2018 AFL season.

[21][22][23][24] Broad played with the club's reserves team in the VFL during the period of his suspension as well as in one further match, before being re-called to senior level in round 5.

[33] That performance, along with consecutive four disposal games to close out the home and away season, saw Broad's continuing selection under some media speculation.

[35][36][37][14] The loss of All-Australian defender and teammate Alex Rance to an ACL injury in that match however, would force Broad into a more defensive role than in seasons past.

[38][39][40][41] His performances were unremarkable over the next fortnight as the Richmond defence conceded 36 goals over two matches, before stabilising with a win over Port Adelaide in round 4 in which Broad ably accounted for opponent Justin Westhoff.

[53] He played in each of the club's unbeaten nine game winning streak to close out the home and away season, including in round 16 when he equaled a career-best with eight marks over Gold Coast.

[59][60][61] In the week that followed, he was the subject of intense media speculation around his fitness to play including revelations that Broad suffered memory loss covering the entirety of the preliminary final.

[67] Broad finished the year having played a career-best 24 matches, winning a second AFL premiership in three seasons and placing 16th in the club's best and fairest count.

[14][68] The 2019/20 off-season retirement of fellow defender Alex Rance assured Broad he would continue to be a key part his club's defensive unit, which he showed with strong performances in the pre-season series including with 21 disposals in the first of those two matches.

[69][70][71][72][73] Broad earned AFL selection for a round 1 win over Carlton when the season began a fortnight later, but under extraordinary conditions imposed on the league as a result of the rapid progression of the coronavirus pandemic into Australia.

[83][84][14] He continued to hold his spot at senior level over the next three matches, including while suffering a dislocated finger in round 5's win over Melbourne.

[85][14] In early July, Broad moved with the main playing group when the club was relocated to the Gold Coast in response to a virus outbreak in Melbourne.

[87] He sat out that and one further match before earning a recall for the club's round 15 win over Fremantle as a replacement for the injured Dylan Grimes.

[94] AFL Media labelled his intercept marking and other defensive efforts as "crucial to the win" in the absence of injured teammate Nick Vlastuin.

[97][98] After a full off-season training program, Broad began the 2021 year with appearances in the club's pre-season campaign and in a round 1 win over Carlton.

[107] Scans later revealed a significant syndesmosis ankle injury, which would require surgery to repair and which would rule him out for at least one month of football.

[114] With the club not qualifying for the final series, the diagnoses would effectively end his season in which he featured in 14 matches and set new career highs for disposals (16.4) and marks (6.4) per game.

[14] Notes Team Individual Broad began a relationship with Love Island Australia season 1 winner Tayla Damir in late 2019.
