By bringing Celtic and Rangers into the fold, there would have to be a major restructuring of the leagues that would make the creation of the Premiership seem like a walk in the park. The various F.A.s involved in uniting into a UK F.A. would try to get what's best for them, and more than likely, the clubs in Scotland, Wales, and Northern Ireland will get the short end of the stick. And imagine how many deserving players will get left off of a unified national team? Some players who play in the lower leagues only get the chance to play internationally because they are from Wales, N. Ireland, and Scotland, and get the call up for those 'countries' international matches. I think the other teams in the SPL ought to just suck it up and deal with the fact that they'll probably never have runs like Celtic and Rangers have had over the last 2 decades, but they can always hope, even with the Old Firm still in the SPL.
