Illo was born in Slovakia. Before coming to the States, he played well in the Slovakian U-18 league, putting up impressive numbers.
2008-09: In his rookie season at the age of 18, he finished second on the USHL Tri-City Storm in points with 21 goals and another 12 assists. Illo accomplished all of this though while only playing 47 games.
2009-10: Scored almost a point a game for Tri-City, posting 24 goals and 19 points in 50 games. Also registered 11 powerplay goals and 56 PIM. Named to the 2010 USHL All-Star Game. Played for Slovakia in the 2010 WJCs where he posted 2 goals and 3 assists in 6 games.
2010-11: Illo skated in 37 of 38 games for Bemidji State. He was second amongst Beavers freshmen with 4 goals and 2 assists and was +3 with 20 PMs. Bemidji State finished 10th in the 12-team WCHA but made a surprise run to the conference semifinals by defeating eventual national champion Minnesota-Duluth in overtime (3-2).
2011-12: Illo skated in 30 of 38 games for Bemidji State as a sophomore – missing eight games after suffering an injury in a February game against Nebraska-Omaha. He scored 7 goals with 10 assists and was minus-eight with 21 penalty minutes. Three of his seven goals were scored on the power play. The Beavers finished ninth in the WCHA.
Illo has the makings of a goal-scorer with a quick release, accurate shot and the ability to find quiet ice to launch shots. He made an early jump to North America, so there are no major adjustments there. Regardless of the venue, Illo would likely have been a project from both a physical standpoint and a skill standpoint.
Illo is just coming into his own as an older sophomore this season with BSU. He will likely play out his full eligibility there and then weigh his options of heading into minor pro or perhaps making the jump back across the pond. While he is not a surefire pro, it may be too early to write him off entirely.
