You might be right. But Friedman is fairly reliable as a source, and if he says multiple teams talked to Dubas about Rust, I believe him. If Detroit and NYR want him, Rust would probably at least think about it, no?
Also, no matter how many Stanley Cup wins a Russian player will earn, his reputation will never be as sterling as a player like Rust. You know it, I know it. It is the sad state of the old boys network that is the National Hockey League.
Bottom line, Rust has more value than you think imho. But we will never know for sure and that is the real crime here.
