Tanev was a bit of a surprise, but given how he has been for us regarding injuries (he was injured at the end of play in March, literally the last game), where Edler, while not injury free, has been more stable on our back end and has been here longer. His next contract could be his last, where as Tanev got his first big contract with his signing in Calgary.
Holtby, should he wash out, will be our problem. We are exposing him, but if he has a good season, I expect him to be selected based on who else we are likely to expose. Roussel? Beagle? I guess one of Juolevi or Lind or Gadjovich or who ever could emerge from Utica could be a good choice too, but the same condition applies: It really depends on the year he has.
I can try to predict, but I agree...there is so much that could change and go differently then what we have now. There are far better goalies out there, no doubt. As far as a duo goes though, I can't see a ton of teams that will have a better goalie exposed. Fleury, should he not be moved is one older possibility. Allen, DeSmith/Jarry, Stalock, Khudobin, Subban/Delia, Georgiev/Shesterkin, Korpisalo/Merzlikins and really those would be my locks for exposure assuming everyone stays where they are. Pittsburgh, Dallas, New York and Columbus have some good assets as secondary goalies, but 3 of them will have a much more unproven goalie exposed (no disrespect to any of them, I'd definitely be looking at one or two of them as a future starter if I were in charge of Seattle), and Khudobin from Dallas has would be my only real worry as a comparable for a "win now" goalie.. He is only being exposed because of Bishops NMC though, and that would be an untenable situation to go into the expansion draft with, IMO. Wild speculating over and done.
