Former Hawks great Terry Wallace has named the teams he believes will improve this season, as well as those he can't quite get a gauge on.

Wallace believes Adelaide, Essendon, North Melbourne and Brisbane will be the competitions biggest improvers.

"I think Adelaide will improve," Wallace told SEN Afternoonsย on Wednesday.

"I just think off the back of the Grand Final two years ago and everything possible going wrong, I think they can improve.

"I think the hyped team of the competition in Essendon will improve.

"I think they're good enough, their squad's good enough.

"If they don't have a stinking start like they did last year. Hopefully they've done more on the track.

"I believe North Melbourne will improve. Their fans will probably be driving off the road because they think that I hate them!

"I think that with what they've brought into their club, if half of those guys play to their potential, a guy like Aaron Hall for example, his best is really good.

"If they can get half of those guys playing to their best, I think they're still in the right age bracket at the moment to improve.

"Brisbane can improve with the list they've put together.

"Those close losses they had last year, they might still finish in the bottom six, but I think they can improve their lot and start to push up the ladder."

All of North Melbourne, Essendon and Adelaide finished on 48 points, just one win away from matching Geelong who finished 8th with 52 points.

Wallace said Geelong, Hawthorn, Sydney and GWS are the sides still in question for 2019.

"They all played finals last year.

"Geelong for me probably still make it because of the home games they get and add that with the MCG games, it's a lot of games in Victoria

"Hawthorn I'm not really sure about.

"Sydney lost six home games last year so there's some questions around that.

"And with the exodus of players, GWS have got to be questionable.

"I think they're good enough, but they'd want to have a good run (with injuries) because they don't have the depth of players they've had."
