Tikkanen was a rare breed. He had the perfect mindset to play the role he did.
He was perfectly comfortable with the fact that Wayne and Jari were the stars, and he never pretended or aspired to be one himself. That mental aspect was Tikkanen’s greatest asset.
Also, Tikkanen had the rare ability to make everone around him laugh (aside from opponents). Some years ago I was at a dinner with some of my Finnish friends. There were around 20 of us, amongst them Tikkanen, Christian Ruuttu, Jyrki Lumme and Petri Skriko, plus a few players who are still active today.
The center of attention (in a good way) was Tikkanen. The other Finns laughed so hard when he told some of his stories (in Finnish) that they rolled with laughter. I could see first hand that he had a very positive effect on the guys around him, even the guys who were more than 30 years younger had a blast. So I can imagine that he had a positive effect in locker-rooms.
In short, Tikkanen was the perfect match for Gretzky and Kurri. While they took care of the scoring, he took care of the rest.
Having said that, he was a pretty good overall player himself.
