I have a feeling that the RFL's desire to have certain teams playing in SL, ......(and of course those teams are essentially attractive to the Sky contract),.....so I belive SL will be expanded in one of two ways.
Just a bigger SL
or
A SL structure based on two equally strong divisions and an included inter-divisional series of matches
One things for sure, the RFL will not want to see Leigh, Bradford, Torronto and any French clubs wallowing around in any division below a SL structure......it's not any good for business that.
