Roberton wasn't a FA either restricted or unrestricted because the player has to have I think at least 8 years/seasons continuous service at their club to qualify.Fair enough I didn't know about the deal from Essendon but I was pretty sure that Roberton was signed up as a delisted FA last year AFTER the trade period.
From memory Roberton was free to go/uncontracted;and if he hadn't had his mind set on going we would have offered him another deal(maybe because it never came to that).
