While I sadly can't tell you much about Suomela as a player - I have never followed his Liiga JYP team - here are some interesting quotes from the Antti Suomela thread on the Jatkoaika discussion forum, just some snippets from various posters:
* Apparently someone had spotted Barrett Jackman (your development coach) watching a game between JYP and Ässät this April. Speculations then were about him either scouting Suomela or Assat junior Kotkaniemi who's up for draft this year.
* Some analyses are saying Suomela's curious talent is to be able to produce in spite of being not flashy at all. No gloried hits, lightning bullet shots etc., just a bunch of hard work, intelligent zone entries, sneaky passes, a lot of good little things. More of a hard worker than a flegmatic artist, if that's the spectrum to rate him in.
* Apparently he had some KHL options to consider before eventually choosing to sign a contract for HIFK for next year.
* If I read the posts correctly, he essentially won the league's top scoring title playing as a third-line center as he only averaged some 16 mins of icetime, which was less than the other top centers on the teams. Someone quoted his ice time being #189 on the entire league this last season, and having had barely if any PK time and only 2nd unit PP time. On the other hand, this also means he maybe hasn't been as tried on special teams as you'd like for a NHL contract signee.
Hope this interests you. I ain't even a regular here (a Canuck fan's what I am) but just wanted to forward this to you since it caught my eye.
