A twenty-centimetre growth spurt has done wonders for the draft prospects of West Australian Tim English, with many observers believing he could be a top-10 pick.

English, now 204cm, was playing school football three years ago for Christ Church Grammar in Claremont, as a 184cm midfielder.

Last year he was captain of that same side and towering over his classmates at 200cm.

The traits English displayed as a mid-sized midfielder his ability to cover the ground and use the ball well have been widely apparent for Western Australia at this year's NAB AFL Under-18 Championships.

"I don't have the physique to body out some of the bigger guys yet so I'm really trying to improve on that," English said.

"That's one of my strengths as a ruckman that I'm able to move around the ground relatively well.

"I've been trying to use that and get on the end of a few offensive chains and set it up in the forward line."
