Phaneuf played rough and tough and laid his body on Michalek with clean hits, and the whole time Michalek had the puck.
Michalek retaliated by spearing Phaneuf and then willingly dropped his gloves. If you frame it from that perspective, then it seems more reasonable - I don't think this is a case of big bad Phaneuf picking on someone unfairly.
I don't even care, Michalek is playing like shit this season so he deserves his ass getting kicked.
That said, the spear was a retaliation to Phaneuf slew footing him, and Phaneuf pretty clearly kneed Michalek while wailing on him, Dion's not exactly innocent.
