The sledgehammer is infallible. It doesn't require skill, precision, refinement, rigor, or exactness. Apply strength; damage done. Still, it's been the weapon of choice for Brendan Shanahan, Lou Lamoriello, Kyle Dubas, and a Toronto Maple Leafs management team that's wielded the handheld destroyer to some effect in demolishing the third-rate organization it inherited. There are swings still to be taken. But now, standing in debris, Shanahan and co. are at a point where they must start building beyond what's been rather brilliantly constructed at the minor-league level. And it starts with deciding whether or not James Reimer represents a pillar in the foundation.
