Compared the last season we've had a relatively injury free run over the past two months, which has seen our results improve. Now we will have to rely on our reserve strength.
If Siro is out then Waddel comes in with Jetski taking his place on the bench.
If Boyle is out (and I question whether he deserves his place in the 17 anyway) then Perrett is probably the best option. Yes, I know, he is a liability in defence. But he can play strongly in attack for 10-minute bursts and I don't think there is another prop in our top 30. (Baldy Saunders or T-Rex are ineligible or else I'd have one of them on the bench).
If Parker is out there are many options imo. I'd suggest the safest one is Cust to 5/8 and move Walker to centre (mind you, I wish Walker would start to have an impact on any game!). Next safest would be leaving Walker at 5/8 and bringing Elliot in to centre. Other options are LG or Croker to 5/8; or keeping Walker at 5/8 and recruiting Funa to centre. I can't see Des taking this last option as it is too risky at such an important stage in the season.
