I like the "bot-cam" for replays only.
I do not like the way rugby is being covered at the moment, as regards the continual changes of camera angle.
In a couple of the test matches in the most recent Autumn Internationals, I counted up to seven camera/angle changes over an eight second period of play from the ball coming out of a scrum/ruck/maul to the try being scored. In one case, the producer did such a good job of outsmarting himself, he actually missed the try being scored in real time, and we only saw it in replay.
There is no need for it. Stay on just the half way wide angle and zoom camera during the live play, then use the fancy angles and sideline cameras during replays or while waiting for scrums & lineouts to form.
I don't know what your SKY TV is like in UK, but we get Discovery and Nat Geo sourced from Australia and the USA, and they have it even worse in their programme promos, with the constant rapid-fire flashing up of shots.... flash - flash - flash - flash - flash... sometimes as many as 50 shots in a 30 second promo. Sometimes watching it makes me feel nauseous.
