Alain Vigneault officially became coach of the Rangers on Friday, his coming-to-Broadway fete staged at Radio City Music Hall, roughly a mile up the street from Madison Square Garden. Vigneault, ex- of the Canadiens and Canucks, has a five-year deal ($10 million total) to bundle up the broken pieces of John Tortorella’s shot-blocking Blueshirts and reassemble them as a Cup contender. General manager Glen Sather, who will turn 70 in September, in a Daily News story last week finally said “style of play . . . had a lot to do’’ with Tortorella’s dismissal.
“I mean, he was pretty successful,’’ Sather added. “He’s a good coach . . . [but] I think the game has changed.’’
