Hateful lowlight: Suspended for dirty hit on Brad Richards

If you're too violent for hockey, you're too violent for this planet. Patrick Kaleta is the kind of dude that will knock you through the glass and then head-butt your unconscious body. He's absolutely merciless, which is fun for blood-curdling hockey fans like us, but rough on the guys who share the ice with him, many of which will perpetually misplace their car keys for the rest of their lives.
