I could see some players being hesitant, but in reality I doubt it's a not knowing where they will play but more just a Canada thing. A vaccine is on the way and for guys signing long term they won't play much in Buffalo.
In the end though, money will talk. If we have the best offer, I think Toronto is a nice city and our team is good enough the players will come. But I don't think they'll pass on LA, NYC, Boston, San Fran, etc if those teams are good and have offers as good because they're more desirable cities.
