Vasilevskiy remains the choice among NHL skaters for the title of best goalie in the world

Published Mon, 03 Mar 2025 23:55:17 GMT

Leon Draisaitl found it hard to answer the question of who’s the best goaltender in the world.“There’s too many good guys,” the Edmonton superstar said.Of course, he did mention one name: Tampa Bay’s Andrei Vasilevskiy, who is considered the best by a wide margin. When NHL players were surveyed by their union for which goalie they’d want to win one game, Vasilevskiy was the choice for over than half of those who answered,. More than a half-dozen skaters asked last month came to the same conclusion.“He’s one of the best goalies to ever play the game — certainly one of the best athletes,” teammate Mikhail Sergachev said. “What is he capable of? Winning a Stanley Cup for us. He can do it by himself.”One problem: Vasilevskiy is expected to miss the first two months of the season after undergoing back surgery. That’s a major headache for Tampa Bay and could open the door for Nashville’s Juuse Saros or one of the two goaltenders in New York — the ...

ACC quarterbacks, sometimes under the radar, are driving success across the league

Published Mon, 03 Mar 2025 23:55:17 GMT

The ACC is off to a promising start this season with several notable non-conference victories and five teams ranked in the Top 25. A common thread is easy to find: Check behind center. The Atlantic Coast Conference, not always known for its strong cadre of quarterbacks, has 10 of the top 60 passers in yards per game this season. That’s tied with the Southeastern Conference for the most among the Power Five leagues, though the SEC and Pac-12 each have three ranked in the top 10 in that category. “As far as the ACC, there’s definitely a lot of talented guys in this league,” said linebacker Jeremiah Trotter Jr., Clemson’s leading tackler this season. And the talent is almost everywhere you look, from North Carolina’s Drake Maye to Florida State’s Jordan Travis, Miami’s Tyler Van Dyke to Duke’s Riley Leonard. “They’re playing the position at a very high level,” Trotter said. None more than Maye, the reigning ACC player of the year who̵...

VATICAN CITY (AP) — Pope Francis shamed and challenged world leaders on Wednesday to commit to binding targets to slow climate change before it’s too late, warning that God’s increasingly warming creation is fast reaching a “point of no return.”In an update to his landmark 2015 encyclical on the environment, Francis heightened the alarm about the “irreversible” harm to people and planet already under way and lamented that once again, the world’s poor and most vulnerable are paying the highest price.“We are now unable to halt the enormous damage we have caused. We barely have time to prevent even more tragic damage,” Francis warned.The document, “Praise God,” was released on the feast of St. Francis of Assisi, the pontiff’s nature-loving namesake, and was aimed at spurring negotiators to commit to binding climate targets at the next round of U.N. talks in Dubai.Using precise scientific data, sharp diplomatic arguments and a sprinkling of theological reasoning, Francis delivered a mor...
