Jarrod Witts is doing well as a full time ruck after doing his ACL last year but yes it'll be up to Schach or Marra to battle for the 3rd tallOur best structured team is probably the one currently picked but Bruce replacing Schache. I wonder if the club is comfortable with Bruce taking the backup ruck duties following his ACL? Otherwise we'd then need to see Schache remain at the expense of Jamarra.
