Got to see Topi play for both Tappara and Tappara U20 so I feel like giving him a bump here.
What he lacks in high-end skill is balanced by a great motor and drive to be apart of the game. For a center he has suitable size at 6'1" 176, still 17 until May.
It is clear his skills are great at the U20 level, but relatively speaking not that "elite". Didn't look out of place in a 4th line checking role in Liiga action, on a top team in the league. I would say the awareness looked good at both levels for 200 ft of the ice. That impressed me more then his technical skills. Not lacking but nothing superb, he's not that much of a scoring threat, good drives to the middle/net and generates offense that way, though the playmaking is pretty good already and I think it will get better thanks to his IQ (pro IQ for sure).
I think middle six center upside is warranted, most likely a good third line center here with the right development tbh.
Early third round would be a great place to get a guy like this, but I could see second round if a team likes the pick.
