Look I hate football but I appeciate that the rest of the world does not share my view on this..so there is coverage of football.Same can possibly go for the Boat race surely.All tastes catered for otherwise tv is going to be excessively boring if only one type of narrow viewing is shown.
Mind I think if this event was opened out to include other university teams it would be much more interesting and more exciting.A two horse race will always be more boring than a 20 horse race.
