The last three years, the Cup winner has found a way to balance skill, size, speed, and snarl. It is difficult, but it's not impossible to assemble a team that has all four elements. Those teams generally win when it counts.
Brawn when it's not paired with skill and skating is pointless, but there is absolutely a place in the game for size and snarl when you stockpile skilled players who also bring that intensity. It will become apparent again in April. Many will forget that lesson by July.
The hockey community is guilty of cyclical remembrance and forgetfulness on this point.
