It genuinely only needs to go for 5 days. The AFL milking this for all its worth. Especially since you have 5 days, then a weekend where no trades can conveniently be lodged, before it finishes midweek? When the news cycle needs ANYTHING because mid week in off season is completely dead.Yep. That's all it is. The funny thing is I'd imagine some of these 'negotiations' and discussions between various clubs would have happened weeks ago. Particularly for clubs that didn't make finals.
It's not like clubs for a lot of deals / players only first discussed trade details on day 1 of the trade period.
It's all just a bit of theatrics to create drama and headlines to further promote AFL and keep the game in the headlines for as long as possible.
You could make the trade period run for only 3-days, nearly the same amount of deals would be done as in the 9-day time frame IMO
If trade week finishes Friday last week, then you have the weekend news cycle and other sports dominating.
I am absolutely certain a ton of trades have been completed by Saturday, and they will drip feed them today, tomorrow and Wednesday.
