Cerra is the last of the top 10 first year draftees to re-commit to their respective clubs.
The No.5 overall pick is glad to stay a docker despite growing up in Victoria.
It is a huge relief to the Dockers after his recent performance against the Adelaide Crows where he had 30 touches in a win.
No.17 pick of the draft, Higgins, is an exciting player to watch as the running midfielder/forward has become a fan favourite in his first year.
Balta has looked dangerous in the VFL, as the key defender has a good kick and blistering speed.
Blues promising tall Pat Kerr has signed on for another year keeping him at the club till 2019.
The 19 year old has played four games this year averaging a goal every two games.
But, the players that most clubs will be looking at is Cats midfielder Tim Kelly and Tigers small forward Shai Bolton.
Kelly has been an important figure at the Cattery averaging 22 touches and just under a goal a game in his first year of AFL. He may request a trade back home to Perth with reports suggesting that him and his family are dealing with homesickness.
Bolton has been shown interest from a few clubs as he continues to show patches of brilliance in the VFL.
