Captain Crash - my dad used to call him 'El Cliffo'.
Many a time I've seen Harris perfectly time and then launch at a receiver who was focusing on the incoming ball, Harris bending at the waist like a jack-knifing diver, and then literally snapping his torso inline just in time to maximize a punishing whallop to the intended target of said pass.
And many a receiver was similarly tattooed and succumbed to that ether liberally administered by Cliff.
Harris hit much heavier than his size. Much.
All us geezers still hail #43. Always, a Cowboys' all-timer.
