MISSISSAUGA, Ontario — Don Cherry, who can be as loud as the jackets he wears during his weekly “Coach’s Corner” segments on “Hockey Night in Canada,” was worried a year ago that he was losing his edge.

He was at risk of becoming a dinosaur, droning on about hockey’s best pugilists when the N.H.L. was turning toward more skill and speed.

After careful introspection, and inspiration from his wife, Cherry, 83, has roared back to being Canada’s Lion in Winter and hockey’s most outspoken voice, well into his fourth decade as a broadcaster.

“Everyone on television knows more about hockey than me,” Cherry said. “But they don’t know hockey. There’s a difference. They know all the stats, they know all the players, the whole deal. But I can pick out things no one else picks out.”
