From Big Footy
Difference between his remaining contract and his injury settlement with the AFL/Club is what gets included in the Cap this year (not a huge difference as it was an injury picked up while playing). As he limped though the NEAFL Grand Final he gets 100% of Senior Match payments for all Matches missed up to a maximum of 30 Matches as well.
And my swans mate said
He triggered an extension for 2018-2020 with his work in 2016
Then was useless in 2017
And Sydney told him to retire and paid him a reduced one off payout now that only counts in the cap for this year
He wanted to keep going
