I think the AFL should introduce a mid-season trade period at the beginning of June to give teams the ability to tweak or bolster their team by trading players with other clubs.
The way it is now, if a team is in a rut and has a deficiency with certain personnel they're stuffed for the rest of the year. With a trade window there would be a chance for clubs to make changes and get some impetus for the rest of the season.
Likewise, there are disaffected players who are wanting out of a side but they have to hang around under sufferance until season's end.
Why not give the player and the clubs a means of striking a deal while the season is still alive?
