No bait, just logic. Football fixtures are announced in June and rugby fixtures announced in November, so there is ample opportunity to ensure that any rugby home games from February to May do not clash with football fixtures that have been set in stone since the previous June. With the introduction of the super 8’s, the back end fixtures should be planned by the RFL to de-conflict with any other pre-planned fixture.
Same with rock concerts – you never see them planned for the same weekend as a home fixture for the sporting clubs that use the stadium. Can you imagine Bruce Springsteen playing the Etihad the night before Man City play a home fixture, or the Rolling Stones playing at Twickenham the day before an England home fixture?
De-confliction is a simple process as long as both parties talk to each other. Having a rugby owner as chair of the football league will help that process immensely.
