Chychrun is a big defenseman coming in at 6-foot-2 220 pounds and is a solid puck moving and offensive defenseman. The Oilers could definitely benefit from adding a player like this into their rotation, and he would certainly help with their run in the playoffs this year.
He currently has 7 goals, 21 assists, and 28 points in 38 games for the Coyotes this year and sits fourth on the team in points despite missing 15 games at the beginning of the year. Now that's not saying much considering Arizona is one of the worst teams in the league but Chychrun has proven he's a great offensive defenseman.
