The 2015 John Worsfold medallist and All-Australian wingman, who joined the club as the No.4 selection in the 2010 National Draft, said he was excited to extend his commitment to the club.
“It’s an exciting time for the club,” Gaff said.
“There are a lot of guys around my age as well as some senior players who are playing some great football, so we’re in pretty good shape. That’s just one of the reasons I’ve re-signed.
“The club has really looked after me since I arrived as an 18-year-old and I have really enjoyed it here. The club looks after its young players through people in the player welfare area like Ian Miller.
“It can be tough as a young player moving over and leaving family and friends, but the transition is made as smooth as it can be. I have been here for five-and-a-half years and it’s great to get the contract done so I can concentrate purely on what we want to achieve in the next few weeks and beyond.”
