The muppetry wasn't necessarily admitting Leigh, although I thought they were an unambitious choice.
The real muppetry was admitting them on the basis that they receive no Sky money, which is appallingly unfair and a really selfish penalty imposed on new clubs by the old guard which started in the Toronto days. Compounding that muppetry was introducing P and R immediately, giving Leigh no opportunity to sort themselves out in the division and making knee jerk decisions like this likely.
