I haven't totally kept up with the moveable feast that the AFL has given GC and GWS, but GC were able to name 17 year olds last year, 10 from memory, that committed them to GC this year. I presume that GWS will be able to do something similar. The point being that, if Jack Vivey is so highly rated, GWS would surely want to grab him ASAP. Does he then have to commit to being a father/son selection a year ahead of time, because of the GWS concessions?
