"I think it's going to be a challenging back to back but we're well aware of where we're at, we're well aware of how we've played to date in back to backs and we've done some really good things." -- Senators defenseman Dion Phaneuf "I think we've got to stop beating ourselves. We're not executing plays. I think it's been pretty sloppy out there. If we can just go back, execute plays and go north, do the small things right, we'll be fine. But we've got to get to that point too. When that happens, we can start building momentum." -- Blues center Patrik Berglund
