It's how they pull the women in Cas Vegas...
Back on topic its practically useless to compare SL teams to Championship teams as it isn't relative. Who's to say Widnes would have done better than Cas or Salford had they been let up back in 2008.
Would several thousand Fax fans REALLY come back to watch Fax if we went up? Would the same be said if Widnes went up? Its proved that it hasn't happened with Salford/Crusaders/Cas.
If you want an argument against licensing, look at Hull KR, they came straight up through P&R and look at them now.
