Friedman did mention Wolf, but he also mentioned Calgary having a reserve list goalie (Arseni Sergeev) in the same age range as Tung; Coincidentally Sergeev was in net for Penn State on the other end of the ice when Tung/UConn were eliminated. Sometimes that's more of the consideration. If Calgary were to sign Sergeev, Tung might find himself in the ECHL instead of the AHL if Devin Cooley isn't promoted to the NHL.
Realistically most NCAA goalies are going to need a couple seasons of AHL time before they even sniff at an NHL backup gig. I still occasionally laugh when I think of the poster who was sure Dryden McKay was going to step directly into the NHL.
The Rangers possibly have more openings. Louis Domingue is UFA. Dylan Garand is RFA. Tayln Boyko is RFA and played mostly in the ECHL. Hugo Ollas is signed for another year but spent most of this season in the ECHL. Maybe the Rangers could give Tung some assurances that he'd have the inside track to the #4 spot?
Even though Garand and Sergeev are both 2002 born, Garand is already finishing his ELC while Sergeev/Tung would be starting theirs. So in a convoluted way there'd be slightly less direct competition.
Plus the Rangers AHL team being in Hartford might have offered some fringe benefit being close to UConn. Not sure if Tung is going to continue with classes or made some close friends in his single season with the Huskies.
