This is a conclusion fans can draw pretty easily based on watching games with their own two eyes without having to look at any statistics. One of them happens to be how bad the defense of the Chicago Blackhawks is. They pinch too hard in their own zone and make errant passes across center ice. The goalies have been left out to dry way too many times.
But if you do want to look at the stats and come to this conclusion, just take a look at some simple categories. The Blackhawks have allowed 96 goals through 26 games, the third-most in the entire league.
