Tatar has three seasons remaining on his contract, carrying a $5.3-million cap hit. His departure results in a huge haul for the Red Wings, who now have two picks in each of the first four rounds of the upcoming draft.
The 27-year-old has 16 goals and 12 assists in 62 games this season.
Through 31 games this season, Jooris has three goals and three assists. The veteran winger has 55 points in 204 career games.
McKegg, 25, has split this season between the Penguins and the AHL. He picked up four points in 26 games with Pittsburgh and 12 points through 28 contests in the minors.
Both teams made additions prior to Monday's trade deadline, loading up for what seems like an inevitable second-round playoff meeting between the Central Division powerhouses.
Which club has the advantage? Here's how it breaks down position by position:
The Jets made a huge splash Monday by acquiring center Stastny from the St. Louis Blues, arguably giving Winnipeg the NHL's best top nine.
Winnipeg has already scored 206 goals through 62 games - fourth-most in the NHL. As we'll see below, that's come with minimal aid from the blue line, and the addition of Stastny will only help them get the puck to the opposition's net with greater regularity.
Stastny to Jets. Winnipeg is one of the best teams in the league moving pucks into the middle of the ice - Stastny excels in that area - precision passer. Jets now have 5 forwards in the top 60 in pass to slot completion %; Stastny is top 30. Easy to argue now best top 9 in NHL.
Nashville addressed an area of weakness from last year's roster by adding depth down the middle in the form of Turris and Bonino, and Fisher is back in the mix as added insurance.
Hartman was brought in via Chicago on deadline day for added scoring, with the Predators having recorded a ninth-ranked 191 goals through 61 games, but with a good chunk coming from the defense.
The highly touted prospect Tolvanen may be an X-factor if he signs his entry-level deal for the balance of the season, but, as it stands, the Jets are stronger up front.

Nashville's defense corps is widely regarded as the best around the NHL, and for good reason.
The Predators are allowing a league-low 2.46 goals per game this season, and everyone but Emelin and Weber boasts a positive Corsi rating at even strength, indicating good puck movement and an ability to keep it away from Rinne.
The Jets, however, aren't far behind. Winnipeg is allowing only 2.61 goals per game (fifth-lowest), as well as one shot per game less than Nashville (31.4 as compared to 32.4).
On top of that, their top six all boast positive Corsi ratings at even strength, and seventh man Chiarot is almost level.
Offensively, however, Nashville gets a big boost thanks to 15 goals from Subban and 10 from Josi. Here are the respective contributions from each team:
Altogether, based on excellence at both ends of the ice, Nashville gets the edge on defense.

Connor Hellebuyck
Pekka Rinne
Michael Hutchinson
Juuse Saros
Rinne played some of the best hockey of his life in backstopping the Predators to the Stanley Cup Final last year, posting a .930 save percentage over 22 games. So far this season, he hasn't tailed off, with a 32-9-4 record and .929 save percentage.
Hellebuyck has an almost identical record (32-9-8) with a slightly lower save percentage (.924), and while he's living up to the billing of one of the game's best young goalies, he brings zero NHL postseason experience to the table.
The Jets may have the better long-term option, but based on the current levels of play, Rinne's run a year ago, and the defense immediately in front of him, the edge in net right now goes to Nashville.
Conclusion
Winnipeg's forward group is as deep and talented as it gets, but Nashville gets the edge on defense and in net, thereby setting the Predators up for the best chance of representing the West once again in the final.
The Jets deserve a lot of credit. They do have a young goalie they're confident in, but they know Nashville has the best defense, so coming out of nowhere and acquiring Stastny is a move they needed to make, especially after missing out on Derick Brassard.
If these teams do indeed meet in the playoffs, bank on the series going the distance.
It marks the third deadline-day trade of Vanek's career.
Vanek joins the Blue Jackets for a playoff push after putting up respectable numbers on a Canucks team with the Western Conference's second-worst record.
Vanek is tied for second in team scoring with 41 points in 61 games.
Meanwhile, Motte has three goals and five points in 31 games this season, while Jokinen joins his fourth club of the season.
The Senators have been talking to teams about possibly dealing the superstar defenseman since at least last week, when McKenzie reported the club was open to trading him.
Karlsson has one more season left on his contract after the 2017-18 campaign with a cap hit of $6.5 million.
"(It's) crazy. One or two points out, move a guy that does a lot for us," Schenn told Jeremy Rutherford of The Athletic. "But at the end of the day, you know, that's their decision."
A pending unrestricted free agent, the Blues dealt Stastny to the division rival Winnipeg Jets in exchange for a two draft picks - including a first rounder - plus forward prospect Erik Foley.
As for the Blues, the team has hit the skids in recent weeks, dropping six straight contests, including two games without a goal. That's pushed St. Louis outside of the playoff picture, one point behind the Calgary Flames for the second wild-card seed.
Stastny departs the Blues as the team's fourth-leading scorer, behind Schenn, Vladimir Tarasenko, and Jaden Schwartz. He has 40 points through 63 games this season.
As Engels notes, Pacioretty could be the most notable winger still available Monday after Evander Kane was reportedly shipped to the San Jose Sharks.
Pacioretty is having a down year by his standards, with just 17 goals and 37 points in 61 games. The 29-year-old scored at least 30 goals in each of the previous four seasons.
He still has one year left on his contract after this year at a cap hit of $4.5 million.
