I don't buy the economic arguments, you can talk them down or up, it will be economically sustainable. It might wax and wane a bit like all clubs and all markets, but it will have flow-on effects outside the internal club bottom line just like GWS and GC, not in the same ways, but it will. 5 million people in Melbourne and 10 clubs. half a million people in Tassie and 1 club. Pretty easy maths. Can anyone think of any example ever in the history of Australian sport when a stadium didn't get built if it was required? *smile* they even get built when they aren't required, (Geelong and Cowboys). When you look at context, national comp, aussie rules state, Tassie being on the up, AFL neglecting Tassie which is having real impacts that need fixing, its a no brainer.
The flies in the ointment IMO is one club needs to go for fixture and national balance, and the talent pool is spread too thin now. Its wrong in my view that Tassie effectively pay for the sins of the past and for the propping up of possible new markets, wrong, but that might stall it for a few more years.
