It has to be remembered that even with the big money that Setanta were pumping into the competition Linfield and Glentoran played weakened teams in some matches. They also never seemed to shut-up complaining about the competition as well. They always appeared to be going on about how the competition favoured LOI clubs and threatened on a number of ocassions to withdraw.
Take away the Setanta money and reduce the prize money and I think the competition simply won't work. The will just isn't there from North of the border.
