Strong-bodied Smithson enjoyed a strong finish to his 2017 campaign with a noteworthy performance, kicking three goals, in SA’s last win against Victoria Country at the U18 AFL National Championships. The boy from Karoonda won the U18 Torrens Uni Cup MVP Award after averaging more than 24 disposals for the Bloods through the midfield. Smithson – who has the ability to hit the scoreboard from the midfield – then tested well at the State Combine, finishing equal first in the 20m Sprint with 2.92 seconds and in the top five of the Agility Test, Running Vertical Jump and Standing Vertical Jump.
