It seems to me that the criticisms levelled at darts as a sport are superficial ones and if the Embassy stage had been filled with bright young twentysomethings this issue would not be an issue. If shooting and archery are Olympic sports then of course darts should be classed as a sport. You don't need to be an athlete to fire a gun or bow, which is also the case for darts. I would like to see the BBC televise more darts and less horse racing. I bet more people watched the Embassy World Masters than the latest Sunday Grandstand's serving of horseracing.
Darts only has the mental aspect of what defines a sport.
Therefore, with that in mind darts is a sport. Rob Morgan, Canada Darts is most definitely a sport and anyone who says differently was obviously born with a silver spoon in his or her mouth. The game of darts requires a great deal of constant concentration and skill. It is one of the most competitive and enjoyable games to play and has by far the most tension and drama than any other televised sport. There's more skill to consistently scoring 180 than throwing 3 darts at the board and hoping they land perfectly on target.
