It happens to everyone not named Gagne. I don't think he will lose his job or anything. He's got more saves than anyone else. I wouldn't freak out, he's gone down this road before and his longtime owners know what to expect out of him and the occasional day where he walks a couple and allows a hit is bound to happen.
