ADELAIDE has signed much-improved wingman Paul Seedsman to a three-year contract. 

The deal keeps him committed to the club until the end of 2021. 

Seedsman, 26, had been sought after as a line-breaking runner, and is ranked No.6 in the competition for metres gained per game this season.

He arrived from Collingwood at the end of 2015 as part of a mega-trade that also involved Melbourne and Port Adelaide.

"My priority was always to stay in Adelaide and it's great to get the deal done," Seedsman told afc.com.au.

"I love it here and the footy club has been fantastic since I arrived, so it's good to be able to repay their confidence in me.

"Even though it's been a frustrating year, the culture here couldn't be better.

"The players and coaches are all committed to getting better and we'll be back up there next year."

Crows list manager Justin Reid expressed his delight at keeping the former Magpie at West Lakes.

"Paul has shown this year what he's capable of on-field, and we're thrilled to have him sign with the club for another three years," Reid said. 

"Our entire senior leadership group have signed extensions in the past 12 months or so, as have a number of key players, so to add Paul to that list shows great unity within the playing group."
