Well that's the third (probably only legal) option. Strip the list.
Do you think that is a reasonable thing to do to require a club which has built its playing list over a number of years in accordance with the rules as they stood to immediately have to divest itself of playing talent?
It's clear that plenty of contributors on this forum do.
"Hawthorn, we've decided that the Tasmania deal gives you too much of an unfair advantage over other clubs. Therefore over the next 2 years we're going to transition that arrangement over to St Kilda. But in the meantime, you are to play all of your home matches (other than the Tassie ones) at Etihad on a late Sunday afternoon. Alternatively, you could drop the Tassie arrangement right now".
List issues
Honest answer is yes - I think it is fair. That is the whole point of the salary cap. It is the reason that Geelong let Ablett go, as well as any number of other fringe players. It is the reason Hawthorn let Buddy walk as well as a number of other fringe players.
Sydney are a premiership side and they have not let any stars go (you could maybe argue Mumford), instead they have recruited 2 massive priced recruits.
No other premiership side has ever been able to do this. And there are a number of reasons why the Swans were able to do it and CoLA (which simply increases the Sydney cap) is one of them. Running a wafer thin list is another, having a compact list not choc full of stars from 2012 is another, retirements have contributed, etc. But notwithstanding all these other factors, CoLA is still a massive factor.
Tassie
The AFL have already tried that on once with the North incursion to Hobart. Ultimately I think the Hawks might be driven out of Tassie but we will see. And then maybe the AFL will park them at Etihad and make them play home games against a rotation of GWS, GC and Melbourne (what we currently get at the MCG anyway - it is a commercial disaster).
However, if you can tell me how that will translate directly to on field performance I would be interested to hear it.
They could do it tomorrow and the Hawks ability to complete on field in 2015 will change one bit.
On the other hand, if the AFL had have given the Hawks a 9.8% CoLA the week before trade week the Hawks would have helped themselves to Ryder, Beams and maybe one other, done the same next year and then gone on to win the next 5 GF's
