An outstanding junior, Jetta was twice named in the Under 18 All-Australian Team as well as being adjudged the joint winner of the Kevin Sheehan Medal, awarded to the Best Player in Division 1 at the Under 16 National Championships.
He was drafted as a player renowned for outstanding pace, good foot skill and terrific vision on the ground.
Despite returning to play with Essendon's VFL affiliate, the Bendigo Bombers, this injury ultimately ended his 2007 season.
As a result of that good form, Jetta earned selection in Essendon's Round 1 encounter with North Melbourne in which he gathered 13 possessions and showcased his terrific tackling.
However, Essendon coach Matthew Knights persisted with Jetta and was paid back by his outstanding performance against Fremantle in round 14.
