I will contribute on some of the Bruins prospects playing in European Leagues and I've seen play a few times on TV here.
In no particular order:
FINLAND LIIGA has been operating with games open to public access and in general had some 2.000 in attendance. However the LIIGA suspended regular season for the month of December due to Corona. They will start in January again hopefully
- Joona Koppanen C-LW 22 6'5" 210 lbs - 10 2+3=5 12 +8. Loaned to Ilves in Finish Tier I Liiga. If there's a sleeper among the B's prospects I would make a case for this big guy. He almost seems to improve with each passing game. After starting out in TIER II with Koovee where he led the team in scoring after 10 games (6G+11A) he was called up to Ilves. In 9 games he's scored 2 goals and 3 assist while playing good two way hockey. Why I like this guy is because the significant improvement he's swhown over the last couple of years plus he's got tremendous size and can still skate very good.
- Matias Mäntykivi C-LW 19 6'0" 170 lbs L - 17 0+4=4 4 -5. This kid has some talent but has mostly wing this season for SaiPa in Finish LIIGA Tier I. I'm not sure his best position is wing as I'd prefer him at center but he's very young. He needs to be stronger and could use some extra gear but Mäntykivi is a very smart and slick playmaker. He's like David Krejci in some small sample. Mäntykivi has played all over the forward lines in SaiPa. From 1st line right wing to third line left wing and some at center. His stats is somewhat misleading but he's playing regularly. He's been selected for Team Finland in the upcoming World Juniors in Canada so maybe those watching will get a glimp of his play.
- Urho Vaakanainen LD 21 6'1" 190 lbs L - 2 1+0 =1 2 +2. Vaaks scored in his first game back in Finland. He's played on 2nd defense pair. Unfortunately he may not play until January due the league has paused play. His next game could be with the Boston Bruins. Can't really comment on Vaakanainen as I haven't seen those two games he played.
CZECHIA
Jakub Zboril LD 23 6'0" 200 lbs L. 14 1+7=8 4 +1. HC Kometa Brno in 1st tier of Czech Xtra Liga. Zboril is thru the warm ups and starting to produce with 1 goal and 4 assist in his last 3 games playing more than 20 minutes a night. Zboril is probably the best of Bruins prospects playing in Europe. He may be their best prospect overall after Jack Studnicka. His skating is outstanding as we all know. He seems very confident and plays with authority moving pucks quickly with a sharp first pass. Sees the ice very well and has a booming slapshot. Very nice to see Zboril keep up the good game he played last spring.
Jakub Lauko LW 20 6'1" 200 lbs L . 14 3+3=6 20 -2. HC Energie Karlovy Vary in Czech Xtra Liga tier I. It's hard not to like Lauko. He's always hustling, 100% effort and has added a little bit of edge to his game. He's bulked up a fair bit so maybe that has something to do. I'm not sure Lauko will ever be a regular point producer. He's game is kind of wild and so are his shots. Many are just swing and miss. Doesn't seem to know himself where to put the puck, just fire away. Seems to be in a bit of rush to shoot, to make plays. If he can find the groove and settle it he may be a good NHL player. His skating and work ethic are second to none.
