Agree there, I think our best balance is two KPDs and two interceptors. I really rate Lachie Young and think he'll be very good in one of the interceptor roles, will probably be best 22 when Wood retires.
Lewis Young is still raw as hell and has development left in him.
My concern about Le Young is his athleticism. Certainly as a defender he's not Hamling like with closing speed, nor is he really strong bodied.
In terms of athleticism he's not to disimilar to Schache (except more assertive in aerial situations). Thats my concern.
