There used to be a lot of little games with coaches hiding players they want to bring back from injury or youngsters they want to bring in. The NRL the coaches do a lot of video work so anything they can hide from their opposite they will do to get whatever advantage they think it may give them.
They have changed the rules as the team naming Tuesday used to be just name last weeks team and move on. Now they name an extended squad and remove players during the week. They may give Leilua to the last possible moment to prove himself as his centre/wing pairing with Rapana is one of their weapons.
Many thanks for this post. As mentioned this is some of the finer detail that I was unaware of and hadn't had explained to me. (I also appreciated the helpful information in the other replies to my post)
Question for you however, if they are delaying to the last possible minute either out of gamesmanship or to give him more recovery time, when exactly is the last possible minute. e,g friday night? or saturday morning?
