2007-08: Nattinen played most of his hockey with JYP U18 (Jr. B SM-sarja) netting 14 goals and 48 points in 34 games. He also tallied a pair of goals and as many assists in six games with Team Finland at the WJC-18.
2008-09: Nattinen played for several teams this season, spending the majority of it with the Blues U20 and seniors squads. In 30 games with the U20 team, he tallied nine goals and 38 points, but failed to register any points in 14 games with the top Blues club in the SM-Liiga. He also skated with the Finnish U18 and U20 teams in their respective WJC’s; he won the Bronze Medal with the U18 squad, scoring a goal and four points in the process. Expect to see him back with the Blue next season.
2009-10: Nattinen would return to the Blues for a sophomore season in SM-Liiga. In 23 games, he would add 3 assists and 4 penalty minutes.
2010-11: One of the top forwards for Finland's national junior teams the past few years, Nattinen had a tough season as a 19-year-old making the transition from the junior level to the SM-Liiga. He was slowed by the effects of an achilles injury and saw limited time in eleven games with his own Espoo Blues club and finished the season on loan to HPK. In 21 regular season SM-Liiga games he had 2 assists and was -8 with 12 PMs. He had an assist and was +1 in one playoff game for HPK. Nattinen also represented Finland at the 2011 World Junior U-20 Championships, scoring 3 goals in six games. Nattinen signed a three-year entry level contract with the Canadiens in May 2011.
2011-12: Nattinen bounced throughout the Bulldogs' line-up and at times was a healthy scratch in his rookie AHL season. He started to adjust to the North American style of play and saw more responsibilities by the season's end. He improved his overall game, scoring ten goals (three on the power play) along with 11 assists and a solid minus three rating in 63 games on an offensively challenged Hamilton team.
2012-13: Nattinen played 24 games for Montreal's AHL affiliate in Hamilton in his second pro season in North America; suffering a season-ending shoulder injury in December 2012. He scored 5 goals with 4 assists and was +6 with 8 penalty minutes. The Bulldogs missed the AHL playoffs after finishing last in the North Division.
Nattinen has a good hockey IQ, creativity and playmaking skills. The two-way centerman reads the play well at both ends of the rink and is versatile enough to play all the forward positions. He can play on both specialty units as well as anywhere in the team's line-up. The big forward needs to play with more physicality and gain more strength to play in the NHL. He has the potential to play in the top-nine at the NHL level if all goes well in his development.
After missing the second half of last season with a shoulder injury, Nattinen will be looking to play a bigger role offensively at the AHL level in Hamilton. He should play on the top two lines for the Bulldogs and will be expected to put up better offensive number in his third AHL season. If the two-way forward can get off to a good start this upcoming season then he could see time as an injury replacement for the Canadiens, should the need arise.
