SL and AFL are extremely different kettle of fish in wise of fan engagement, competition, sponsorship.
Cowboys only move stadium which is now in centre of Townsville, which has issues with car parking and (I lived in Townsville for a few yrs), public transport. A lot of the locals didn’t want A new stadium, they would of preferred it on a upgraded dam.
Where did you get figures for storm and dogs ? NRL, DT, RL project? Eels just temporary moves location till bank west was built, as Bank west is in the same location as their old stadium.
I think upgrades would help both sharks, pennies and the rest. Though as proviously stated, completely new stadiums which are huge, expensive and the expectation of them to being filled, used for numerous events will only hurt the game and centralising teams will not help the game
