Scottish Rugby chairman John McGuigan admits the new rebel league is a potential threat -- and could have a dramatic effect on the game at both domestic and international level. A slimmed-down fixture list has also been put on the table, offering an attractive alternative for international players who have grown tired of overloaded match schedules. Though sceptical about the logistics of such an operation ever coming to fruition, McGuigan said it was something that rugby could not now shy away from - as competition for wages and contracts increases in the pro game.
