Alwyn Junior could attract a bid inside the first 20 or so selections on draft night after an exciting season with the Oakleigh Chargers and Vic Metro, while Jayden sat out the year after undergoing his second knee reconstruction but is also a highly talented small forward.

The pair have boarded at Xavier College in Melbourne in recent years, having grown up being in the changerooms at the end of their father's 100-game career with the Bombers, and have also been a part of Essendon's father-son program.
