I thought nothing of him during the 2017/2018 WHJC, but defenitely saw improvement during the tournament in 2018/2019. Think he played pretty big minutes but can't find the ice time stats.
Anyway, he went from 12 points (2+10) to 20 points (6+14) this season in Lulea's U20 team. He also went from a -5 to a +25 player, and was assigned team captain. Near the end of the season he was called up to the SHL. He was credited with a game, though he didn't get to play a single shift. The offensive production saw an increase in the WHJC too, going from 0 points to 3 (1+2) in 5 games.
Still, he's more of a defensive defenseman and that's gonna be his bread and butter at the pro level. But improving on his puck moving skills and shot from the point will defenitely help him. The improvements he made this season could've only happened due to hard work. Hopefully he contineus that way. He may never make the NHL full time, but I would not be surprised to see him sign a deal somewhere within the next 3-4 years and get a cup of coffee in the big league.
Whatever happens, he's another young name worth pointing out that could help the national team, just like Bodak and Ivan. Speaking of "older" players, I remember liking Mislav Rosandic a lot during his WHJC campagin some years ago, and I see he was close to making the national team for this WHC. All in all, I think Slovakia are in fairly decent shape on the back end. But goalies and centers are big needs.
