Leafs Coaching and some remedies

I feel Ron Wilson, is a stubborn coach slow to change, but he would be a better coach if he was more flexible in his thinking. Two sore spots I see the Leafs develop this season are a defensive zone coverage by their defence, and penalty killing. There has to be ways the defense can work to become better, some are fundamentals, lifting sticks, poke checking, sweep checking, tieing up sticks in front of their net, and penalty killing don`t have their box shrink, have it expand and be more aggressive. we`ll see if they adapt.
