It's a "nice" idea, but doesn't really work and wouldn't really help.
Firstly, to simply not LOSE money, TSVL crowds need to be as big as Cairns.
Then you have to somehow grow the crowds. Few people are going to be able to travel to games in the other City. You'd get some growth from casual fans, ie those who might only attend half a dozen games anyway, but overall I think the Logistical Nightmare outweighs any benefits.
As for the roster,
Have to wait and see how good these new imports are, but so far not impressed. Had to give Kelly the benefit of the doubt last season, but this time they need to show they can be competitive.
