There were plenty who thought JOC (James O'Connor) (James O'Connor)'s experience was insufficient and that his strength was 12. Personally I'd prefer he was still here, but I doubt we will look back in 12 months and be thinking "well, what would have been if JOC (James O'Connor) (James O'Connor) had been backing up 10".
Creighton (Wiki) is listed with 34 Red caps to Lynagh's 22 - noting Lynagh is pretty much all focussed at 10, whereas Creighton is flyhalf, centre, wing, FB. Did he have any more experience than Tom at flyhalf? Also Lynagh's introduction into pro-rugby has been one of the most considered and progressive I have seen recently.
Reds have young 10s to be sure, and like I suspect all Aus Super clubs the depth of experience and ability is possibly "under development". All the same I am happy with how we are sitting as we line up the 2025 season.
