I hope it works but suspect it won't. This appears to be another approach to expand - this time into a RU hotbed (East Midlands) and I suspect it will be doomed to failure. Attempts to try expanding RLs boundaries have met with very limited success in UK, the only team of any "distinction" being Harlequins RL/London Broncos/Fulham.
Kent, Wales (North and South), Nottinghamshire, Gateshead have all flirted with pro/semi pro rugby and failed whilst Sheffield Eagles keep bobbling along.
Perhaps if some Saints stars crossed over for the summer it might take off? Dunno?
