Tuch is a player whose style is better for the pros than college. They'd be crazy not to try to sign him. He's a legitimate NHL prospect, albeit a low ceiling.
Kapanen - I don't think he'll be in Finland. He'll either go to the SHL (one team is believed to be ready to make an offer) which is a bit of a stronger league or North America.
Biondi is a forward, not a d-man. Also, while it wasn't mentioned in the article, he opted for a fifth college season last week so the deadline doesn't apply to him.
