Nathan Horton doesn't think the concussion he sustained in Jan. 2011 is a factor anymore. Horton was limited to 46 games last season with post-concussion syndrome. "I'm not even worried about my head," Horton said. "Or being in contact. Or getting in a fight. I feel better than I have in a long, long time." His agent, Paul Krepelka, also recently said that Horton was "ready to go."
