Apparently Hak isn't the only one that likes to do it.

"Yesterday, Quenneville set the Twitterverse on fire by changing up the lines that had carried the Hawks through their Game 4 and 5 victories over the Los Angeles Kings. The biggest change was the one that saw Patrick Kane and Jonathan Toews, who had clicked so well in the previous two games that Kane had scored four goals, separated once again."
You would think a Stanley Cup winning coach would know better than to change things at the end of the year & especially in the Finals.
GO HAWKS!!!
