5. Israel Folau – Rugby League to AFL
Israel Folau joined Karmichael Hunt in the AFL after being offered a massive deal with the Greater Western Sydney Giants and despite his natural athleticism Izzy was never able to make it in the AFL.
Thankfully, his third code swap was far more successful and he has developed into a key member of the Wallabies side, but anybody that watched his kicking during the his time with the Wallabies would question how anybody ever thought he could make it in the AFL.
