Because all of our forwards think about is dumping the puck in and chase (or change).
Good teams like MTL never stand around waiting for a pass. They always move around to receive passes and quickly transition the puck up to their streaking forwards.
Maybe 2-3 times out of 10 we breakout with the puck. The rest is all dump-ins, which is almost the same as giving the puck away because we barely get it back (except when Hogs' after it)
