It is an interesting side. I must admit I have never seen Ryan in the centres and have my doubts about Benji playing there. For mine if Lui or Arana was fit I would pick them at half instead of Lazarus.
For mine I like the bench with maybe the only change being Fulton staring for Gower. Fulton is a player like Stagg and Dallas Johnson a defensive machine and should be on the field as long as possible.
Would feel a lot more confident with CT bench going into a match than with the current bench we have for most games.
Ryan is a better centre than he is a winger or fullback. Spent most of his juniors there.
Lui and Taumata both aren't halfbacks, Lazarus is. Blake gets the nod in front most due to his long range kicking game, something the WT desperately lack. Although in saying this, Lui has worked hard to develop his kicking game to add to his repetoir. With having Ayshford at 6 as a ballrunning half and link man, that is why i can not justify Taumata and Lui as the 7 due to both of them being ballrunning halves as well.
No doubts with Marshall's defence at centre because he already defends out there and is usually sided with better tacklers anyway. Not much would change with Marshall's attack except he won't be able to squeeze the backline out of space. But this also does not restrict Benji to run across to the other side of the field to link up with a straight running forward or drift across to the other wing.
Fulton being a tackling machine and does deserve big minutes, but as i've stated before, Gower is no slouch either. Fulton was put to the bench to cover several positions as the utility.
