The issue is, what would happen in the premiership?
It's fairly obvious in Ireland that Leinster are the favoured team, with most of the Ireland squad playing their, despite the central contracts. Those centrally contracted players benefit from playing with their international teammates at their club, having centrally contracted players in England spread across, whatever number of prem teams the RFU and PRL want, doesn't have the same benefit. I can see the RFU trying to keep it to 4 clubs.
So who would be the favoured clubs in England?
I think despite the fact they got kicked down a league for cheating, Sarries would be one of them,
Leicester likely to be another down to Borthwick,
Quins obviously with all their chums across the road a third,
so who would be the 4th team,
Chiefs unlikely as despite their success they never really had a lot of internationals, plus Tony Rowe,
Bristol unlikely as well due to the non-english contingent there (despite their great training facilities)
It won't be Sale or Newcastle, can't have the northerners involved
Won't be London Irish for obvious reasons
If we assume it won't be Wasps or Worcester as they are deemed Champ teams (or lower) (Although I think Wasps would have been a good option with their training facilities)
That leaves Bath, Glaws or Saints.
All 3 are traditional strong supported English clubs, and I'd have one of them before Sarries in a heartbeat, I think it would end up being Bath as Glaws probably deemed a but too small, and Saints too close to Tigers (I think it should be Saints before sarries).
So if it does end up being Sarries, Tigers, Quins & Bath, what does that mean for the rest of the prem, do we end up with a 2 tier league?
