The Flames' Dennis Wideman knocked NHL linesman Don Henderson to the ground on Wednesday with a vicious-looking hit from behind.

The big debate Thursday: Did Wideman do it on purpose? Based on my watching of the video, I'd say yes. Wideman gets up after being knocked to the ground, perhaps is upset that a penalty wasn't called on Nashville, skates toward the bench with Henderson in plain view and knocks him to the ground.

But maybe you see other shades of grey? Maybe you believe Wideman when he says, "I was just trying to get off the ice. And, at the last second, I looked up and saw him, I couldn't avoid it."
