The Edmonton Oilers are blessed with something that is the envy of the rest of the league: the best hockey player in the world, Connor McDavid. Not only do they have McDavid on their roster, but they also have one of the NHL's most prolific scorers in the form of Leon Draisaitl.NHL Public Relations@PR_NHLConnor McDavid's season has been catching the eyes of not only fans but also peers around the NHL. The McDavid show continues tonight at 7:00 p.m. ET on NBCSP, SNW when the @EdmontonOilers put their eight-game point streak on the line in Philadelphia. #NHLStats758Connor McDavid's season has been catching the eyes of not only fans but also peers around the NHL. 👀 The McDavid show continues tonight at 7:00 p.m. ET on NBCSP, SNW when the @EdmontonOilers put their eight-game point streak on the line in Philadelphia. #NHLStats https://t.co/UyeLAb6v1D"Connor McDavid's season has been catching the eyes of not only fans but also peers around the NHL.

However, if Edmonton's General Manager Ken Holland is able to put the right pieces around the current roster, the Edmonton Oilers may be able to add another ring to their collection.While the team may have two of the top players in the league, it is not without its faults. The defense has consistently been one of the biggest weaknesses for the Oilers and will be the main facet of the roster that they need to address. Here are three players that the Edmonton Oilers may add before the NHL Trade Deadline:#1 Luke SchennLuke Schenn may be exactly the kind of player that the Oilers need. Given that the Vancouver Canucks have already made a significant move by sending Bo Horvat to the New York Islanders, Schenn will certainly be on the move as well.The Hockey Writers@TheHockeyWriterEdmonton Oilers Blue Line Trade Target: Luke Schenn#THW #HockeyTwitter #LetsGoOilersthehockeywriters.com/oilers-defense…Edmonton Oilers Blue Line Trade Target: Luke Schenn#THW #HockeyTwitter #LetsGoOilersthehockeywriters.com/oilers-defense…"Edmonton Oilers Blue Line Trade Target: Luke Schenn #THW #HockeyTwitter #LetsGoOilers" - The Hockey WritersSchenn is the ideal defensive defenseman that could help the Oilers make a deep postseason run. A two-time Stanley Cup champion with the Tampa Bay Lightning, Schenn would also provide the Oilers with championship experience. Given that his contract is only $800,000, it would be an easy contract for the team to absorb.#2 Jakob ChychrunThough likely a much higher price tag than Luke Schenn, Arizona Coyotes defenseman Jakob Chychrun is one of the most sought-after defensemen on the market. Not only would Chychrun be an excellent addition to the Edmonton Oilers' defensive core, the fact that he is only 24 years old means he would align perfectly with the age of the team's stars.Dyl@dhockey13“How many times have you asked and prayed that the Oilers would trade for Chychrun?”627“How many times have you asked and prayed that the Oilers would trade for Chychrun?” https://t.co/gEsl3j0sB4“How many times have you asked and prayed that the Oilers would trade for Chychrun?” - @dhockey13#3 Erik KarlssonErik Karlsson would be the best-case scenario for the Oilers. However, the San Jose Sharks will likely demand a king's ransom for the former Norris Trophy winner. If Edmonton is willing to pay up for the veteran defender, he may be the piece to push the team over the top.Joshua 💣@BouchBombsIf the Oilers trade for Karlsson or Chychrun imma be hoping back on the bandwagon twitter.com/OilerAlert/sta…Oiler Alert@OilerAlert“3 months ago I would’ve said no on Chychrun, 2 months ago I would’ve said probably not.

The Oilers and Sharks may need to come to a salary-retention agreement depending on the trade.
