Willie Rioli, the cousin of Hawthorn superstar Cyril, was among those to impress at South Australia's NAB AFL Draft Combine on Saturday.

Rioli ran 2.98sec for the 20m sprint and showed improvement in his beep test, registering 13.2. The small forward/midfielder lost 16kg in the pre-season to put himself in contention to be picked up by an AFL club.

The 21-year-old booted four goals for the SANFL in the representative clash against the VFL in May.

West Adelaide's Conor Noonan looms as the most likely of those in attendance on Saturday to end up on an AFL list and he was among the best performers. He took out the beep test with 14.4 and also did well in the agility test.

Noonan is an outside midfielder who stands 182cm and shows smarts up forward. An injury-riddled year meant he played only one game in the NAB AFL Under-18 Championships, despite having been desperate to show recruiters what he could do.

Liam Mackie, whose cousin Andrew has won three premierships with Geelong, was another to show his wares at the state combine.

He registered 13.3 in the beep test and 3.04sec in the 20m sprint.

At 186cm, Mackie is a half-back who reads the play well and provides accurate kicking from defence. His wiry frame is yet another attribute he shares with Andrew.

Others to stand out were Dylan Whimpress, who ran the 20m sprint in 2.91sec. At 188cm, the medium defender combines speed and a high leap, and can also play forward.

Tye Bedford (a speedy wingman) and Peter Ladhams (ruckman) tested well in the running vertical jump.
