Beating the good teams then putting up absolute stinkers against bottom dwellers is an aggravating staple of both teams.
And the solution seems to be putting guys on their off-wings where they are very uncomfortable and have a harder time clearing the puck from their own end. "Hey, lets take a team that already has trouble getting the puck out of their own end and make it even harder!"
Just because guys like Neal and Dupuis can play both sides doesn't mean every player can.
"We didn't get to our game". This is total apcray, which simply means that they are not ready to play games. You need to have an attention to details, like a solid clear of the puck, or a deep dumpin to let lines change. When you don't do these things, you are just being lazy, and that has to do with being ready to play and give what is necessary in every game. This team doesn't have it at the moment.
