BUFFALO, N.Y. — Testing at the NHL Draft Combine doesn’t begin until Saturday, but team representatives, agents and prospects all gathered here this week, leading to plenty of league chatter. Especially with the decentralized draft — teams now operate from their own facilities — it’s a prime time for face-to-face meetings.In addition to holding the No. 5 pick in the first round on June 26, New York Rangers president and general manager Chris Drury will face major decisions in free agency and on the trade market as he retools a roster that finished last in the Eastern Conference this season.Here are some Rangers-related news, notes and thoughts from conversations I had with league sources in Buffalo this week.Looking at Larkin?Thursday’s trade request from Detroit Red Wings captain Dylan Larkin is obviously a seismic shift in the NHL offseason landscape. My sense is, at this point, the Rangers aren’t on his initial list of desired teams. That doesn’t mean Drury can’t try talking to Detroit and making a compelling offer to see if the 29-year-old center would eventually be receptive to a move.Even if Larkin winds up interested in New York, hurdles would remain. For one, the Rangers might have a tough time matching other teams’ offers, especially if they don’t want to subtract too much from a roster that lacked the depth needed to withstand the injuries it suffered last season.A potential Larkin trade will also have ramifications for the Rangers even if they don’t get involved in the talks. Vincent Trocheck is no longer the top center on the trade market, raising questions about how much Larkin’s availability could shift a potential return for New York.Nonetheless, Trocheck will draw plenty of interest. Perhaps even the Red Wings look at Trocheck if they move Larkin and don’t get a top-six center back in return. If that happens, New York would likely need to receive a quality young player (potentially Nate Danielson or Marco Kasper), a pick, or a combination of the two in return — as well as potentially a player like J.T. Compher, who could slot in at center behind Mika Zibanejad and J.T. Miller.Colleague Vincent Z. Mercogliano reported after the trade deadline that Drury was looking for “an NHL-ready forward with top-six potential as the centerpiece” of a Trocheck deal.Potential in-state helpThe Sabres have a few intriguing players the Rangers should keep an eye on. With Alex Tuch inching toward hitting the free-agent market on July 1 and the Rangers presumably seeking wing scoring, he makes obvious sense as one option. But Buffalo’s tightness against the salary cap — even if they don’t re-sign Tuch — could lead to other players shaking free.
