When the Vegas Golden Knights selected  Deryk Engelland  in the expansion draft and signed  him  to a one-year deal  the longtime Las Vegas native set out to earn another contract.
 Engelland  got  it  Monday with a $1.5 million  one-year extension that serves as a reward for the veteran defenseman enjoying  his  best NHL season at age 35.
“That’s a dream come true ”  Engelland  said. “I’m getting a little older now and to be able to stay here at home and play another year  that’s your whole goal going into the season and I couldn’t be more happy.”

 Engelland  is averaging almost 20 minutes a night and has three goals and 10 assists for 13 points through 41 games. General manager George McPhee said  “Deryk has been an integral part of our team  on and off the ice  from the very beginning.”
 Engelland  has always been somewhat of a tough guy and came into the season with 500 penalty minutes in 469 games with the Pittsburgh Penguins and Calgary Flames.  He  has just 16 this season and has show  he  has more to  his  game than that.
Roy added that  Engelland  and coach Gerard Gallant having similar personalities helped them get and stay on the same page.  Engelland  is the blue-collar  veteran leader on a young team  while Gallant is the front-runner for the Jack Adams Award as coach of the year.
 Engelland  fell in love with Las Vegas while playing for the ECHL’s Wranglers from 2003-2005  and  he  and  his  wife  Melissa  still call  it  home.  He  was thrilled when McPhee approached  him  about an extension that gets  him  a raise from  his  current $1 million salary and about the Golden Knights’ success thus far.

Example Input: Leading up to the Olympic figure skating menâs event   Nathan Chen  was a gold medal favorite.  Chen âs teammate Adam Rippon  who does not perform some of the more difficult jumps that  Chen  does  wasnât considered a true threat for a medal in the olympic skating menâs event  but managed to endear  himself  to the world with  his  exuberant â and clean â skate.
Now Rippon sits ahead of  Chen  after the Olympic figure skating menâs short program. Ripponâs error-free skate  albeit minus the quad jumps  landed  him  in seventh place while teammate Vincent Zhou is in 12th.  Chen   who made mistakes on all of  his  jumps  is currently 17th. That means  he  will skate in the second group of six skaters in the free program tomorrow  since the skating order is reversed from the rankings after the short program.
 Chen   who is competing in  his  first Olympics  is having a tough time so far. First there was his error-filled short program in the team skating event earlier this week  in which he botched all of his jumps. Then he did the same in the menâs short program.
 Chen âs arsenal of quadruple jumps sets  him  apart from most of the competition; quadruple jumps are worth far more in points than triples are  and itâs easy for  Chen  to add up points and pull away from the field â if  he  lands them cleanly.
The disastrous short program prompted tweets of encouragement for  Chen   including from Olympian Scott Hamilton. âI respect you. I admire you. I believe in you. Today was a difficult day. Tomorrow is up to you!â
But even if  Chen  skates a dazzling long program peppered with multiple quad jumps  itâs numerically impossible for  him  to climb from 17th place into medal contention â unless most of  his  higher-ranking competitors all come down with the norovirus. âIâve never been in this position before so I donât really know exactly what to do â  he  says.
Even before the menâs short began  Olympian and silver medalist Paul Wylie questioned the fluidity and uncertainty of so much of todayâs Olympic athletesâ schedules.  Chen  has said  he  regularly changes the elements of  his  program  switching jumps depending on how  he  is feeling and whether  he  needs to perform the more challenging ones to game a competition. âI am not a fan of the ultra fluidity of the planned program content â Wylie said. â Nathan  is dealing with a lot of variables. The other variable is  Nathan  is always talking about  his  boots;  he âs got three different pairs of boots. And  he  has been going away [from Gangneung] to practice. So  he âs thinking  where am I practicing today. Iâm not sure those question marks are really what you need in the Olympics.â
Maybe what  Chen  needs is some of teammate Ripponâs infectious exuberance. âIâm able to go out in the individual menâs event and show the world I am a cutthroat competitor and that Iâm an awesome skater â Rippon says. âAnd I want to show why everyone should be involved in skating because it is something that has brought me so much joy  and can bring a lot of other people a lot of joy as well.â

Example Input: A day after a report raised the possibility that the NCAA could have done more long ago about problems at  Michigan State  President Mark Emmert  said Saturday in an email that sexual assault allegations against Spartans athletes in 2010 were “widely reported” and already being investigated by law enforcement and the school.
 Emmert  made the comments in an email to the NCAA Board of Governors and other university presidents. Spokeswoman Stacey Osborn provided  Emmert’s  email to The Associated Press in response to a request for comment about a report by The Athletic that cited a letter sent in 2010 to NCAA leadership by the National Coalition Against Violent Athletes.
 Emmert  noted that  he  met with the coalition’s Katherine Redmond and legal expert Wendy Parker in November 2010. A letter sent by  Emmert   dated Dec. 6 and addressed to Redmond and Parker  was also provided to AP. It detailed programs the NCAA was helping to implement on campuses to address sexual violence and student behavior  though it made no specific reference to Michigan State.
As for his role   Emmert  told the NCAA board in his email: “The MSU cases were widely reported in the press and already being investigated by law enforcement and university officials. Kathy did not imply that these were unreported cases or that she was acting as a whistleblower to report unknown information to the letter’s recipients.”
