here's the full restricted and unrestricted list: https://www.foxsports.com.au/afl/afl-free-agents-2018-full-list-of-restricted-and-unrestricted-free-agents-revealed/news-story/a8b301c82a07505f2e59fb420687de26
with the exception of sloane, gaff and lynch, i think it's unlikely you'd prise the restricted free agents away from their clubs, so instead in terms of bringing free agents in you look to the unrestricted list, and the ones i'd be keen on would be, in order:
luke dahlhaus
tom liberatore
nick smith
obviously key to retain t mac and jetta
