Before we get to the top five, lets take a look at some Honorable Mentions because there were some great players left off of the main list.
Some of these names will be very familiar to Caps fans, and one might make a valid case that they should have been in the top five.
Some of these players were left off the main list primarily because their best seasons were not really with the Caps. They all had great moments during the 1990s. But when you compare their body of work to the five best players of the decade, I felt that these guys came up a little bit short.
The current head coach of the Capitals had some productive years in D.C. during the '90s. Oates played in Washington from 1996-2002 and was an integral part of the 1997-98 team that reached the Stanley Cup Final. During the 1990s, Oates had 49 goals and 164 assists with the Capitals.
But those numbers are nothing compared to the numbers Oates put up in the earlier part of the decade while playing for the Boston Bruins.
For instance, Oates' best season ever was during the 1992-93 season with the Bruins, when he scored 45 goals and had 97 assists for a career high 142 points.
By contrast, his best season in D.C. during the '90s was in 1997-98, when Oates had 18 goals and 58 assists for 76 points.
Oates is one of the best players ever and one of the better players of the 1990s. But most of his damage was done playing for teams other than the Washington Capitals.
Kevin Hatcher was one of the better defenders in the history of the Washington Capitals. But the bulk of his career in D.C. took place in the mid-1980s.
Still, Hatcher's best season, statistically speaking, was the 1992-93 season when he scored 34 goals and had 45 assists. In fact, though Hatcher played more seasons with the Caps during the 1980s than the 1990s, he was far more productive in the '90s.
But by the 1994-95 season, Hatcher's tenure in Washington was over. He finished out his career playing for the Dallas Stars, Pittsburgh Penguins, New York Rangers and Carolina Hurricanes.
As good as Hatcher was, when you match his career up against someone like Calle Johansson's, Hatcher just was not quite up to par.
Joe Juneau scored what might be the biggest goal in Capitals history with his goal in Game 6 of the 1998 Eastern Conference Final against the Buffalo Sabres.
Despite that one glorious moment, Juneau was never really all that spectacular for the Caps.
He was a good player, no doubt about that. But it would be a stretch to call him a great player.
Juneau played in Washington from 1993 to 1999. During that time, Juneau scored 62 goals and had 172 assists. His best season in D.C. was the 1995-96 season, when Juneau scored 14 goals and had 50 assists.
Those are very solid numbers, but that's nowhere near the year Juneau had with the Boston Bruins in 1992-93 when he scored 32 goals, added 70 assists and had 102 points.
Overall, I just don't believe Juneau was one of the greatest players of the 1990s for the Caps.
Of all the people left off the main list, I struggled with Dale Hunter the most.
Hunter is, after all, one of the most popular players in franchise history. His goal in Game 7 of the Caps' 1988 playoff series against the Philadelphia Flyers is right up there with Juneau's goal against the Sabres or Joel Ward's Game 7 winner against the Boston Bruins as one of the most iconic goals in Caps history.
It got even harder to leave Hunter off the list when one considers that his best season ever was during the 1992-93 campaign, when Hunter scored 20 goals and had 59 assists for a career high 79 points.
But it was what happened after that regular season that swayed me to leave Hunter on the Honorable Mention list.
The problem began with the check Hunter laid on the New York Islander's Pierre Turgeon in Game 6 of the 1993 Patrick Division Semifinal, generally regarded as one of the biggest cheap shots in NHL playoff history.
Hunter had to serve a 21-game suspension for that hit.
His production for the Caps was never quite the same after that. He would score only 52 more goals for the remainder of his career with Washington.
Of course, Hunter had a lot of intangibles which aren't accounted for by pure stats, such as his leadership and toughness.
But when you look at Hunter's entire career, and particularly during the 1980s which began with the Quebec Nordiques and ended up with the Caps, one could argue that his best years were in the 1980s and not the 1990s.
Relegating Hunter to an Honorable Mention was a tough call. But compared to the other players on this list, I think it was the right call to make.
