Ryan McDonagh hopes to make his debut with the Tampa Bay Lightning in about a week.

The former New York Rangers defenseman has been sidelined for the past nine games with an upper-body injury.

The Lightning acquired McDonagh on Monday in exchange for forward Vladislav Namestnikov, prospects Libor Hajek and Brett Howden, a first-round pick in 2018, and a conditional first rounder in 2019.

In 49 games with the Rangers this season, McDonagh netted two goals and 24 assists.

The 28-year-old is signed through the 2018-19 campaign.

Patrick Maroon will have fond memories of Edmonton.

So much so that the new member of the New Jersey Devils is open to returning to the Oilers should he reach unrestricted free agency this summer.

"Nothing but good things to stay about this organization," Maroon said, as per Sportsnet's Elliotte Friedman.

The veteran forward has played alongside Oilers superstar Connor McDavid since arriving in Edmonton in 2015. Last season, he posted a career-high 27 goals and 42 points.

Maroon, 29, carries a $1.5-million cap hit this season. Given he's tallied 30 points through 57 games this year, he could be due a sizable raise come July.

Erik Karlsson didn't go anywhere, but there were still a few major moves on this trade deadline day.

A quick flurry of midday activity and then a typically timed barrage of transactions around the 3 p.m. ET buzzer punctuated the day, but some teams made out much better than others.

Here's a look at which clubs excelled and which ones faltered on the day of the NHL's trade deadline in 2018:

Winners

Winnipeg Jets

The Jets made a move no one saw coming (how often does a team beat the insiders to the punch for a significant swap on deadline day?), landing Paul Stastny from the St. Louis Blues. His acquisition turns one of the best top-nine groups in the league into arguably the NHL's deepest.

Sure, Stastny is a pending unrestricted free agent, and Winnipeg gave up a couple of conditional picks (including a first-rounder) as well as college forward Erik Foley to get him, but it's a worthwhile gamble, given Stastny's passing ability and faceoff prowess.

Jets general manager Kevin Cheveldayoff deserves credit for capitalizing on the Blues' losing streak that reportedly put the plan to trade the center in motion, and Winnipeg will only be on the hook for 50 percent of the strong two-way player's $7-million salary.

Tampa Bay Lightning

Steve Yzerman didn't get Karlsson, but he landed quite the consolation prize in Ryan McDonagh - as well as talented winger J.T. Miller - in a blockbuster trade with the New York Rangers.

The Lightning GM certainly paid a price for the duo, but didn't have to give up as much as he could have, considering the two impact players he got in return, and also considering the package he would have had to part with if he'd pulled the trigger on a deal for Karlsson.

Tampa Bay ultimately bolstered its roster for a potential Stanley Cup run with two key pieces while parting with two picks, two less-than-elite prospects, and Vladislav Namestnikov, who has 20 goals this season for the first time in his career, and who benefited from playing alongside Steven Stamkos and Nikita Kucherov.

Miller and Namestnikov aren't too far apart in terms of skill, but landing both McDonagh and Miller was clearly going to cost the Lightning, and this move was certainly smarter for Yzerman than giving up multiple first-rounders, a better prospect, and the likes of Mikhail Sergachev and/or Brayden Point for Karlsson.

Detroit Red Wings

Yes, the Red Wings could have jettisoned Mike Green, but GM Ken Holland made up for that in spades by dealing Tomas Tatar to the Vegas Golden Knights for three picks - a first-, a second-, and a third-rounder.

Tatar's a skilled scorer who will no doubt boost the Golden Knights' offensive attack, but that's a huge return for a player who, despite some moderately productive seasons, has never topped 29 goals and who is still on the books for three more seasons at a cap hit of $5.3 million.

Losers

Buffalo Sabres

The Sabres succeeded in trading Evander Kane before the deadline, but that's hardly an accomplishment worth lauding considering the disappointing return in the deal.

Buffalo only managed to get a conditional 2019 first-round pick (which reportedly drops to a second-rounder if the pending UFA walks in free agency), a 2020 fourth-rounder, and 24-year-old prospect Daniel O'Regan.

Just how bad was this for the Sabres? To put it in perspective, the Chicago Blackhawks essentially got more for Ryan Hartman and a fifth-round selection (a first-round pick, a fourth-rounder, and prospect Victor Ejdsell) than the Sabres received for Evander Kane.

Vancouver Canucks

Jim Benning didn't get enough for Thomas Vanek, plain and simple.

The Canucks GM failed to land a draft pick in his deal with the Columbus Blue Jackets, who, settling on journeyman forward Jussi Jokinen and prospect Tyler Motte.

Benning's hands were tied to a degree at the deadline with the Sedins opting to play out the remainder of the season before deciding on their respective futures, but to not land a single pick in either the Vanek deal or the Brendan Leipsic-Philip Holm exchange with the Golden Knights should be seen as a failure.

Columbus Blue Jackets

The Blue Jackets have had major trouble scoring (only the Sabres and the Arizona Coyotes have fewer goals per game this season), and they didn't do enough to address that Monday, settling for Vanek, the 34-year-old deadline-day staple who potted 17 goals in 61 games playing with the Sedins.

Jarmo Kekalainen, the Blue Jackets' GM, also grabbed Mark Letestu from the Edmonton Oilers on Sunday, but neither move is likely going to move the needle enough on the offensive end, but considering some of the better scoring forwards that were available, Columbus should have landed one of them.

To be determined ....

New York Rangers

The jury is still out on the Rangers' haul in the deal that sent McDonagh and Miller to the Lightning, but it doesn't look too favorable.

While the Rangers could have done better, they certainly could have made out worse by comparison.

We'll need much more time to fully evaluate this one from the Rangers' perspective, but it's a haul that will clearly continue to stir debate.

The Ottawa Senators plan to offer captain Erik Karlsson a contract extension if he remains with the team this season, GM Pierre Durion told Postmedia's Bruce Garrioch.

While Karlsson is still in Ottawa following Monday's trade deadline, several teams were reportedly interested in acquiring the superstar blue-liner.

"Erik is a franchise player and we felt there was no franchise deal out there," Dorion told Garrioch.

Karlsson can sign an extension with the Senators as early as July 1, but the possibility remains that the team could consider trade options prior to that day, potentially at the June draft.

In 56 appearances this season, Karlsson has five goals and 37 assists.

The Pittsburgh Penguins and forward Patric Hornqvist are "very close" to agreeing on a contract extension, general manager Jim Rutherford said Monday.

Hornqvist, 31, is scheduled to be an unrestricted free agent on July 1.

"Over my career, I've done very few contracts in the middle of the year," Rutherford said following Monday's NHL trade deadline. "I think it says a lot about what Patric Hornqvist means to us to do this now... If everything goes well, the deal should be done tomorrow."

The gritty, two-way forward has 17 goals and 32 points in 51 games this season.

The Montreal Canadiens have acquired defenseman Mike Reilly from the Minnesota Wild for a 2019 fifth-round pick, which was previously acquired from Washington.

Reilly was drafted 98th overall in 2011 (fourth round), and has four goals and 14 assists in 84 career NHL games.

He's spent the bulk of his professional playing days in the AHL, where he's averaged 0.52 points per game.

His addition offsets the Canadiens dealing Joe Morrow to Winnipeg earlier in the day.

The Montreal Canadiens have sent defenseman Joe Morrow to the Winnipeg Jets for a fourth-round selection.

The New Jersey Devils acquired forward Patrick Maroon from the Edmonton Oilers on Monday, Sportsnet's John Shannon reports, according to Sportsnet's Elliotte Friedman.

In return, the Oilers acquired a third-round pick in 2019 and a prospect, according to Friedman.

Maroon's production has dropped after he put up 27 goals and 42 points last season. In 57 games, he's tallied 14 goals and 30 points.

The 29-year-old adds depth to the Devils' left side after the team picked up Michael Grabner from the New York Rangers last week.

The Calgary Flames acquired depth forward Nick Shore from the Ottawa Senators on Monday, Sportsnet's Elliotte Friedman reports.

In exchange, the Senators acquired a seventh-round draft pick in 2019, according to Bruce Garrioch of the Ottawa Sun.

Shore appeared in six games with the Senators this season, collecting one assist. Ottawa recently acquired him in the deal that sent Dion Phaneuf to the Los Angeles Kings.

In 49 games with the Kings this season, Shore registered four goals and 11 assists.
