That might be a good start. You don't answer a question with a question. I asked anyone to produce evidence of saying anything other than "dumb to drop Kafusi into coverage". In other words, actual times it is good to drop a lineman into coverage. Now that dropping Kafusi actually was a good move they change their tune.
So the question needs to be answered - did someone a year ago say that Kafusi should only be in coverage in X situation - or were they just blanket comments that Kafusi in coverage was just stupid?
