Rugby
I have to admit, and I have no shame about it at all, that I have never seen a live match of rugby either league or union. I've watched a few on the telly where at least you can sit in the warmth and comfort of your own home and get yourself a good hot cup of tea and a nice fat slice of cake at half time. (I have seen one football match and believe me one football match at Millmoor was quite enough to put me off ever standing on any cold wet terrace ever again.) The difference between union (southern, rich and amateur) and league (northern, poor and professional) was explained to me during my teenage years. Then again many, many years have passed and that could have been the other way around. However it strikes me that the edges have become distinctly blurred and the more I look the more blurred they become, except of course for the number of men on the field, oh and some slight differences in the rule book.
Rugby League

Five years ago Superleague Europe sought to bridge the gap between winter playing amateur sides and the Summer Superleague sides by forming an elite Summer Conference completion. This was latterly called The Rugby League Conference. The Conference was divided into North/South/East/West divisions throughout England. Rotherham's success on the winter field was rewarded by an invitation to join the is Conference. Each of the Clubs were to be affiliated to Superleague Clubs and would have access to professional coaching and management input. Rotherham were mated with Huddersfield Giants hence they play under the banner of Rotherham Giants and play in Huddersfield colours which are Claret and Gold. The winter side play in red/white/blue. Interestingly a number of Rotherham Rugby Union members have played for Rotherham, notably John Dudley. Information from Ian 2004.
