Earlier in the day, the young pivot was quizzed by club staff on a variety of topics during a formal interview.
It was one of "25 or 26" meetings Kotkaniemi remembers participating in over the course of his stay in Western New York.
"That was a pretty good meeting," recollected Kotkaniemi. "I knew before the meeting that they were looking for a center, so I thought that could be me. I tried to be sharp when I went in there. I knew that it went well and they were pretty comfortable with me."
Even so, the interview portion of the annual event did cause the Pori native some stress. But, he managed to keep it in check with the help of some of his countrymen.
"I came to Buffalo with Rasmus Kupari and Sampo Ranta. I spent whatever time I had with those guys," said Kotkaniemi. "We would talk about the meetings we'd already had. It was good to hear what other teams had told them and what kind of guys you'd be talking to."
When it was Kotkaniemi's turn to put his physical attributes on display, he was equally keen on being sharp and maintaining his focus, too.
In retrospect, the public nature of the testing at HarborCenter didn't distract him one bit.
"It's kind of the same thing like what you have during games. You kind of forget the crowd and you just focus on what you're doing," insisted Kotkaniemi, who felt prepared for the tests courtesy of his training back home in Scandinavia. "In Finland, we practice a lot and we're running a lot and lifting weights more than here in North America, so I was ready when I got there. It was good."
