Trindall is a 7, using him as utility or 18th man has stunted his development imo. If you aren't using him as starting 7, then don't use him at all and let him play in reserve grade where he can keep developing and mature in that position every week. I wouldn't even put him at 6 now if Moylan was out, have Dykes have a run or shift Hynes to 5-8. He played well last few games when he was a starting half at top grade which is a good sign.
I would give current halves combination one more season to get right or improve, but if game management is the same problem, I'd be looking for a proper half for 2024. If the plan is set for Hynes Moylan combo for next 2 seasons, then that's the risk we take not looking at or going to market Nov 1 for a top halfback for 2024. I just hope we don't have same results as this year for next 2 seasons
Kennedy also on notice, if he doesn't improve defense start of next season, bring in Dykes and start building his game for the rest of that season or just have him first choice. Kid is confident and always tries to get involved, ready for top grade, could have a break out season 2024 when we need it after him consistently playing next season.
I don't mind paying 800k+ for an experienced top halfback if we could afford it, you'd be strengthening your spine. You will also get the best out of Hynes or Moylan, who can have a bit more freedom to play their style
