In 2014, Mihocek signed with Victorian Football League (VFL) club Werribee for 2 seasons after looking to move on from the EDFL. He won the Player's Player award in 2014,[9] playing in the Werribee Development side. In 2015 Mihocek was in and out of the senior team, but played in Werribee's elimination final loss to Collingwood, and was one of Werribee's best.[10] He was also selected to play in the 2015 AFL Victoria Young Gun's game. When Werribee became aligned with AFL side North Melbourne at the end of the 2015 season however, Mihocek sought a move to another club.
2016–2017
Mihocek met with Port Melbourne coach Gary Ayres in the offseason, and crossed over to Port Melbourne for the 2016 season searching for team success.[11] Mihocek played 33 games for Port Melbourne over 2 seasons and kicking 15 goals. He had an impressive first season and was awarded the Jack McFarlane medal for the club's best and fairest in 2016. Mihocek's 2017 season was interrupted by injury, but he returned in the second half of the season and played a key role Port Melbourne's 2017 VFL Premiership. Mihocek primarily played in defence and excelled in the role, but he was also very capable when asked to play up forward.[12] He was looked at by several AFL clubs at the end of the 2016 season as a rookie draft selection, but it wasn't until the conclusion of the 2017 season that AFL side Collingwood contacted Mihocek and informed him that he would be selected by the club in the rookie draft,[citation needed] and he was ultimately selected with pick #22 as a key defender.
AFL career
Mihocek primarily plays as a tall marking centre half-forward in the AFL, but he has the capacity to also play in defence; either as a key defender or loose man at the end of the game. At the forefront of Mihocek's game is a strong mark which allows him to play both ends as a tall, as well as an accurate kick. Additionally, he is also capable of floating up onto a half-forward flank or wing and play a link-up role to send the ball forward. The most notable facet of his game is his work ethic and selflessness as he is constantly running, applying pressure and leading in the forward half to present as a target.[citation needed]
2018
Collingwood had been watching Mihocek closely in the Victorian Football League (VFL), and chose him as pick 22 in the 2018 rookie draft. While he played primarily as a defender in the VFL, he made his debut as a tall forward against Fremantle in round 11 of the 2018 season to immediate effect, kicking 4 goals. He found himself a regular in Collingwood's best 22, playing every remaining game in the season,[citation needed] including the finals series and the Grand Final loss against West Coast where he kicked 1 goal.[citation needed] He finished the season with 29 goals from 16 games.[citation needed]
2019
Other Collingwood's forwards had injuries and suspensions; Mihocek played regularly. He received 4 Brownlow Medal votes in 2019.[citation needed]
2020
The reigning leading goalkicker for Collingwood, Mihocek started 2020 in top form, and was leading the Coleman Medal during round 6 with 12 goals. However, after this Mihocek struggled with inconsistent form, as did the Magpies, and only managed 8 goals from the remaining 10 games he played in the home and away season. This poor showing was compounded after a sickening collision with Melbourne's Aaron vandenBerg in the first quarter of their round 12 match left Mihocek knocked out cold. This resulted in him missing round 13, the first time he had missed a game since his debut, putting an end to a run of 52 consecutive games. Mihocek returned to form in the first week of the 2020 Finals series with a 3-goal performance, and was Collingwood's best player in the tense final quarter, getting on top of defender Jeremy McGovern to kick 2 crucial goals, and at the end of the match moving behind the ball, cutting off West Coast inside 50's to help get Collingwood over the line. Mihocek ended the season with 25 goals from 18 games, leading Collingwood's goalkicking for the second consecutive year.[citation needed]
2021
Despite kicking 34 goals and being Collingwood's leading goalkicker for a third straight year, Mihocek, along with Collingwood struggled in 2021, as the Magpies fell from a semi-final berth in 2020 to 17th on the ladder in 2021. He kicked 34.34 for the year with an accuracy of 42.5%. Mihocek had a career-best game against the Gold Coast Suns in round 7 picking up 24 disposals including 20 kicks, collecting 12 marks, and kicking 4.2 in a loss. He was suspended for 1 game in round 22 for a bump on Brisbane player Tom Fullarton, the first suspension in his career, and only the second time he had missed a game.[citation needed]
2022
Mihocek started the 2022 season strongly, picking up three bags of 4 goals in the first 13 rounds, though missing the round 5 match with COVID-19. This strong form coincided with a resurgent Collingwood outfit who put a shocking 2021 season behind them to entrench themselves in the top 8. Mihocek's form peaked against reigning premiers Melbourne in round 13, where he clunked 10 marks and bagged 4 goals to drive a massive upset victory. The second half of the season saw Mihocek struggle with niggling problems and a hip injury he picked up after a contest with Mason Redman in round 19 that caused him to miss the following week. Unfortunately, his form tapered off after his return as Collingwood surged into a preliminary final, though his presence up forward to crash packs and assist teammates was still valuable. Mihocek finished the season with 41 goals, his best return, and led the Pies' goal-kicking for a fourth consecutive year.[citation needed]
^The 2020 season was played with 17 home-and-away matches per team (down from 22) and 16-minute quarters with time on (down from 20-minute quarters with time on) due to the impact of the COVID-19 pandemic.
