Green totaled 360 points (113 goals, 247 assists) in 575 games with the Capitals. That included a career-high 31 goals (18 on the power play), and 73 points, all of which led the League for defensemen in 2008-09. He also ranked first among defensemen with 19 goals, 57 assists and 76 points when the Capitals won the Presidents' Trophy in 2009-10.
This season, he has 28 points (six goals, 22 assists) in 54 games. That includes 13 points (one goal, 12 assists) on the power play.
But, as nice as it sounds, bringing back Green would not be a perfect fit for the Capitals. He is right-handed and would not play ahead of the right-handed defensemen in their top two defense pair, Matt Niskanen and John Carlson.
An experienced left-handed defenseman who could play alongside Carlson in the second pair would be a much better fit. Rookie Christian Djoos has been playing in that spot for much of the past two months.
Djoos, 23, has great offensive potential, scoring 13 points (three goals, 10 assists) in 46 games, but his size (6-feet, 169 pounds), strength and inexperience make him a question mark heading into the playoffs.
There's no question Green would be an upgrade over rookie Madison Bowey, 22, a right-handed defenseman who has played most of the season on the Capitals third defense pair. But what price would the Capitals be willing to pay to upgrade?
Although the Capitals (32-17-6) are in first place in the Metropolitan Division with 70 points, they are not the powerhouse they were last season when they won their second consecutive Presidents' Trophy, which included going all-in and acquiring defenseman Kevin Shattenkirk from the St. Louis Blues before the 2017 NHL Trade Deadline.
The Capitals acquired Shattenkirk, along with goaltender Pheonix Copley, in exchange for forwards Zach Sanford and Brad Malone, a first-round pick in the 2017 NHL Draft and conditional draft picks. It was a steep cost for a rental defenseman who played on their third defense pair and on the power play - the same role Green would play.
The Shattenkirk trade made sense at the time, but didn't work out how the Capitals hoped. They lost in the playoffs to the Pittsburgh Penguins in the Eastern Conference Second Round.
After giving up a first-round pick for Shattenkirk, would the Capitals do it again - or give up similar - to trade for Green? That seems unlikely.
