Whether or not this is true, there has never been any evidence presented that he wanted to stay in Tampa.
The only evidence is that Tampa made an initial offer. There is no evidence that his agent brought a counter offer. There is no evidence that Tampa made a subsequent offer.
Tampa making an initial offer doesn't infer anything about what Raddysh wanted. Last year Toronto made several offers to Marner. Does that mean that he wanted to stay but they couldn't come to a deal? Not at all, Marner's mind was made up not just that he was leaving, but where he was going to.
As for looking for alternatives, if he told them that his plan was to sign in Toronto, that makes the looking for alternatives pretty simple.
There were people like Kyprios, and at least one poster on this board who claims to know the family, who months ago said that Raddysh was coming to Toronto for family reasons. Not maybe coming. Definitely coming. Maybe they were making that up, but evidence far more supports their claims.
