From today’s New York Times, an article by Kim Severson:

Mr. Lowe liked that Track, a forward, was extremely focused and aggressive on the ice. If he could manage his temper a little and improve his shooting, the boy could have gone all the way, he said.

The temper was a longstanding problem. Hockey is a raw sport, but Track pushed the limits and often got kicked out of games in Wasilla and at least once in Michigan. The parents who had watched Track grow up on the ice said he was very popular with his teammates and generally a pretty good student. But on the ice, he was an animal.

An animal?
