There has been quite a bit of friction between AAFC and PFA about what exactly a second division would involve.
PFA is adamant that full professionalism is an absolute necessity, while the AAFC is pushing for something which seems like it would be (at least somewhat) semi-pro.
The AAFC’s original ‘Championship’ model, released in 2017, required that clubs were capable of an annual budget of $2.5 million. PFA went public at around the same time with their own modelling, which put the number at $5.5 million.
By way of comparison, A-League clubs seem to be in the $10m-15m range, with the bigger clubs (SFC, MVC) “probably closer to 20 than to 10” (Lyall Gorman in an interview about 2nd-div at the time, which is the most recent source I can find).
Assuming a second-division was somehow made viable according to PFA’s specifications, then it seems reasonable that its clubs would be able to make the step up financially (though, as an aside, whether the reverse is true is a whole other unknown).
A couple of million in broadcast revenue (HAL clubs currently get $3.??m/year), an extra 20-30k at the gate across a HAL season and an extra $5/ticket from their existing crowds, plus increased sponsorship and corporates, would bridge the gap between a stronger 2nd-tier side (lets say $6m) and the bottom of the 1st-tier (lets say $10m).
The AAFC’s model, obviously, not so. The gap is way too wide, it would really need to be wildly successful beyond their expectations, and remain so beyond the novelty/honeymoon stage. At best, if a few of those teams were individually successful, then hopefully it makes the expansion process easier for them, which then drives more expansion hopefulls to invest in building up their ‘Championship’ clubs.
