I think no matter who they selected as 18th man they would have played the day before.
Usually the 18th man stays with the First Grade squad but sometimes they do play the lower grade game too (ISP or U20s) as was the case with Ayshford.
The mistake here was they were so confident in Foran playing that they brought Aysh in as a formality more than anything. Also, the ISP are top of the table and played last year's Champs so would have wanted to field a strong side.
End of the day no one could have foreseen Foran being a late scratch besides the League gods who hate us.
I think you're right there, but I can't say I agree with how the Warriors have prioritized in this case.
Do we put up a full strength reserve side or take one/two of their players and throw them onto our extended bench just in case they're needed? For me it's an obvious decision, the reserve grade side isn't the priority. It's there so our other players can compete for positions and stay match fit. Winning in reserve grade doesn't mean anything if it's at the expense of the first grade side.
I think it's bad judgement from the coaching staff personally.
