ANOTHER final, another Rioli best-on-ground.

Richmond father-son prospect Maurice Rioli jnr, 18, delivered a sharp reminder as to his credentials for this year's NAB AFL Draft on Saturday night. 

The son of the late 1982 Norm Smith medallist dazzled with four goals for St Mary's in their semi-final win over Nightcliff to book a berth in the Northern Territory Football League Grand Final. 

Rioli is eligible to join Richmond, Fremantle or Essendon via the draft but has previously indicated his desire to play in yellow and black. 

His father played 118 games for the Tigers and 168 for WAFL club South Fremantle, meaning the talented small forward qualifies for Richmond and Fremantle as a father-son.

Essendon also has ties to the Tiwi Islands as part of their Next Generation Academy zone. 

Rioli has followed in cousin and 2015 Norm Smith medallist Cyril's footsteps by boarding at Scotch College in Melbourne.

The youngster also has a close bond with cousin and Richmond premiership player Daniel, the pair having also spent time together at the Tigers. 

Maurice Rioli jnr is the nephew of former Essendon player Dean and is related to West Coast premiership forward Willie Rioli and St Kilda defender Ben Long. 

He is expected to play for the NT Thunder in this year's NAB AFL Under-18 National Championships.
