One of the new breed of Lions that made a strong impression in 2006, Stiller started the season on the club's rookie list, yet by round three he made his AFL debut against St Kilda. He saddled up again in round four and then returned to the AFLQ, before gaining another call-up in round 12. From that point, Stiller didn't look back, remaining in the side for the rest of the season. From rounds 12 to 15, Stiller notched up 97 disposals - including 28 touches against Carlton in a best-on-ground effort in just his fourth AFL match.
