The Rangers’ wait continues on Alex Kerfoot’s small “d” decision, with the free-agent center from Harvard “still processing” his options as of late Tuesday, according to one individual familiar with the situation. But as the Rangers — and Canucks, plus perhaps another finalist in the bidding for the 23-year-old — awaited word, the Blueshirts did make a small “m” move in signing one-time Devils winger Bobby Farnham to a professional tryout, under which he will attend training camp. The 28-year-old Farnham is an agitator in the Ryan Hollweg mold. He will be trying to earn a contract, let alone secure a spot on the opening-night roster, for an organization that is light on NHL-ready forwards down below and is all but bereft of that ilk from top to bottom. If Kerfoot does sign with the Rangers, the club would have 49 players under contract, one under the league maximum. There is a possibility they might invite at least one other player to camp on a PTO.
