The thought that giant prop Nelson Asofa-Solomona is still on the improve is enough to send shivers down the spine of most opposition clubs but that’s exactly what the Melbourne Storm big man is expecting.

Asofa-Solomona has been one of the Storm's most consistent performers in 2019, with the big Kiwi putting together his best season yet since debuting for Melbourne some four years ago.

The 23-year-old is averaging a career-best 114.9 running metres a game this season and leads the Storm in offloads (25) despite the fact he hasn't played more than 50 minutes in any match this campaign.

Asofa-Solomona said it took him some time to settle in Melbourne and only now is he maturing as a player, with his best years still ahead.

"My game has definitely improved a lot over the last few years," Asofa-Solomona said.

"I am playing more minutes and I feel I have more of a leadership role.

"It is a lot to do with maturity. When you are young you don't really put up your hand.
