What Waterford must do to drive over the edge and into utopia

I saw an interview with Ken McGrath during the week where he expressed the hope Waterford would just go for it tomorrow against Kilkenny. 

Ken felt it was Waterford’s best chance.

Ken’s attitude, and hope, is mirrored by every hurling supporter, probably even some people in Kilkenny. They want to see the abandon and have-a-cut mentality shown by the Waterford U-21s. But is that really going to happen?
