His large size (over 6'8 ft tall) combined with his hard slap shot was the most convincing factors that influenced Sakari Pietilä to suggest him to the Blackhawks.In 2007–08, Anttila scored his SM-liiga career-high when he racked up 23 points in 56 games, and he was selected to play for the Finnish National team during the European Hockey Tour.After parts of three seasons with Örebro HK of the Swedish Hockey League, Anttila returned to the KHL, linking up on a one-year deal with Finnish-based club Jokerit on 20 April 2016.[2] During the 2016–17 season, having added a physical presence to the checking lines, Anttila agreed to a two-year contract extension to remain with Jokerit on 8 January 2017.[3] Anttila remained with Jokerit for six years before the club's withdrawal to the KHL before the playoffs in the 2021–22 season due to the Russian invasion of Ukraine.
