Pavel Dorofeyev is heading to the New York Rangers as part of a trade at the NHL draft on Friday night, as they hope the high-scoring winger helps supercharge their retooling effort.The Rangers acquired Dorofeyev from Vegas for the Nos. 26 and 92 picks this year, plus a conditional first-rounder in 2028. The 25-year-old is coming off scoring 12 goals on the Golden Knights’ run to the Stanley Cup Final.On their way there, they defeated the Utah Mammoth, who also made a big subtraction by sending a winger to the Eastern Conference. JJ Peterka is going to the Boston Bruins for the No. 23 pick and Florida’s top-10-protected ’28 first-rounder. Peterka is changing places for a second consecutive offseason following his move from Buffalo just over a year to the day ago. The 24-year-old from Germany now gets to play for the league’s only German coach, Marco Sturm.

“I would like to thank JJ for his commitment to our organization,” Utah general manager Bill Armstrong said. “JJ is a great person and will be a dynamic player for Boston.”Midway through the first round, the St. Louis Blues acquired forward Mason McTavish from Anaheim for the Nos. 15 and 29 picks, getting a player entering his prime at 23 who’s signed through 2031 at a salary cap hit of $7 million. The Mammoth flipped the 23rd pick to Detroit for 23-year-old restricted free agent goaltender Sebastian Cossa.
