Derek Roy has enough issues. The Buffalo Sabres' center has a balky shoulder that will likely keep him out of the lineup tonight in Toronto for the second straight game, he's on pace for his worst offensive season in six years and he's getting plenty of blame from fans for the team's continued struggles. Now there's this: Roy is the hottest name in the rumor mill if the Sabres make a trade. There are all kinds of rumors out there, most of them from little-known websites lacking much credibility. But it's quite a bit different when your name gets mentioned on "Hockey Night in Canada.""
