Today marks the start of the AFL’s month-long window for player movement, incorporating the first ever period of free agency.

From October 1-19, restricted and unrestricted free agents have the option to move clubs, while the trade period, which has traditionally lasted for one week, has been extended in 2012 and will run from October 8-26.

Stay in touch with all the latest Richmond news from the free agency/trade periods with Tiger Trade Central, brought to you by Bingle Car Insurance.

How does free agency work?
Players can change clubs without going through the process of a trade or the draft.  A concept that has long been a part of American sports, free agents fall in the category of unrestricted or restricted.  To be eligible, players must be out of contract and have spent at least eight full seasons at one club.

Restricted versus unrestricted
An unrestricted free agent can automatically move to the club of his choice while an offer to a restricted free agent can be matched by his club, which has right of first refusal over his services. A restricted free agent is one that is in the top 25 per cent highest-paid players at his club while an unrestricted free agent is in the bottom 75 per cent or has spent at least 10 years at his club.
