Probably not the greatest example but going in Simon Brown-Vincent Pettway was seen as great chin/big puncher match up with most people thinking Brown's great whiskers would give him a clear edge.
We all know what happened here after Brown floored Pettway early, the big punch overcame the great chin to chilling effect.
