Replays are not often inconclusive. In fact they are rarely inconclusive. Now you could point to the fact that rarely is not never. But then again, the technology is not being implemented, except by the TV company, and only in a way that suits them for overall pictures, not for the good of the game.
As for using the imperfection strategically, do they not do it already..? It's a done argument, Fran. It's only a matter of when the technology is implemented, not if. They might as well get it over and done with, because the technology has better eyes than the officials. Goodness knows we've expected a general level of performance out of them each week that has been simply unobtainable without help. Video technology will help the officials achieve that.
