Its a roster issue, simple as that.
Look at our second row options…
Fulton is a moral.... Blair failed so was shifted out, so fit options are Pettybourne, Thompson, Sue possibly, BMM. Fulton pulling the full 80, leaves you honestly with Petty, Bodene and BMM 3 man rotation. Who knows if they will turn up or go full potato, and at some stages they will also have Blair at prop to possibly compound the issues. Potter has dropped BMM, and hedged his bets on rotating Pettybourne and Thompson this week it seems.
You then come to Lock, Fulton could do it well enough, but your still down a second rower, I dont think Sirro has the chops to slot in the hole yet either. Do you drop Sirro and pull a prop back, and put who on the bench? Spence? This is where I dont understand Groat not being promoted.
Potter doesnt have the options at present, we all prefer Anasta in the halves, but going old school ball playing lock is about all we have at the moment, it has to be his train of thought. If it wasnt you would think Fulton would be 13 and Braith 12, where he started the season. It would have only taken say Bell to be healthy and I am guessing Braith would be in the halves and Sirro back in NSW cup. Its rough to string Potter up over this team list when you take it all into consideration.
