BUFFALO — The next four weeks might prove to be some of the most important in recent Rangers history, and the club knows it.

The front office was all up here in Western New York this week for the NHL combine, where one-on-one interviews with prospects were taking place from Monday through Friday, after which the players would speak to the media and then go through physical testing. It was a lead-up to the draft on June 21 and 22 in Vancouver, where the Rangers have four picks in the first two rounds, including No. 2-overall.

“Big picture, we’re just trying to get ready,” assistant general manager Chris Drury told The Post this week. “We have a lot of picks, traded away a lot of good players to get these picks. So we’re just prepping the best we can to get ready for Vancouver.”

All eyes will be on the Devils with the No. 1-overall selection for the second time in three years, set to take either American center Jack Hughes or man-sized Finnish winger Kaapo Kakko. Whichever one falls to the Rangers is just fine with them, as both players are regarded a cut above the rest of the draft.

“It was exciting for all of us and all of our fans to watch the lottery unfold, and we ended up in a great spot,” Drury said, with the bounce of the ping-pong balls having moved the Rangers up from No. 6 to No. 2. “Being one or two, both Jersey and us are very excited. The position we’re at, we’re going to get a real good player.”

The 18-year-old Kakko, standing at 6-foot-2 and 200 pounds, was impressive while helping his team win gold at the World Championships. That tournament just finished up on Sunday night in Slovakia, and so he went back to Finland and decided to pass on going to the combine. There was hardly any reason for him to show up, and his absence did not effect the way the Rangers think about him at all.

“We totally understand where he’s coming from,” Drury said. “Guys miss for various reasons, and it doesn’t really change anything for us.”

Drury called Kakko’s performance in the tournament was “impressive,” as he tallied six goals in 10 games. But it was not meant as a slight to Hughes, who stands 5-foot-10, 170 pounds, and managed three assists in seven games while the U.S. fell one win short of a medal.

“They’re both terrific players, extremely high-end talent, different type of players,” Drury said. “You don’t want to look too much into a two-week tournament. Different teams, [Hughes and Kakko] playing different roles, being asked to do different things. Both are extremely gifted and talented players.”

Yet most of the work now is with how the Rangers will deal with the rest of their picks. They have another in the first round at No. 20-overall, coming from the Kevin Hayes trade to the Jets. They then add two in the second round — No. 49 coming from the Mats Zuccarello trade to the Stars, and No. 58 coming from last year’s deal that sent Ryan McDonagh and J.T. Miller to the Lightning.

The Rangers already traded their second-round pick (No. 37 overall) to the Hurricanes in exchange for the rights to Harvard defenseman Adam Fox, who signed his entry-level deal and is set to be in training camp come September. Also set to be in camp will be the team’s top pick from this previous draft, 19-year-old Russian forward Vitali Kravtsov, taken No. 9-overall as the first of three first-round selections.

It seems like a long time ago that the organization sent “The Letter” back on Feb. 8, 2018, but a lot has happened since. As they plod along this path of rebuilding, the next few weeks will prove vital towards finding future success.

“It’s the most important draft we have,” Drury said, “because it’s the next one.”
