its as simple as a bad coach...
i explained this many times, how all a teams need to do to beat the Leafs is double team Matthews, and clog the slot.
Keefe had no answer for that deployment, and never made an adjustment, and if you review every series loss, this is basically how they shut down our offense.
we pepper no chance shots from the outside, or pound away at the puck up against the goalies pads in too tight, so, shot totals get high, but the actual chances to score are slim.
So, all the other team needs to do is pressure our sucky D and wait for the inevitable turnover in the slot and score a 'soft' goal, where the goalie had no chance, but then blame the goalie anyways for not being able to make a save when we need it.
