Yeah that's a good question I don't know. I questioned the year off straight out of school that cohort had in 2020 but Sam Walker and Walsh are fine.
Howarth had a year off too and has Bellamy, but he's trended a similar path of up and down. But I think Howarth is starting to show an somewhat upward movement slowly.
Piakura has now trained fulltime since 21 and played 29 Cup games and 30 NRL games so you should see some improvement in these elements of his game but there just isn't yet.
It's been Piakura's whole career not just this year, I have lost count of the number of games I have commented- fixed that now, for him to miss 10 tackles the next week.
Even the Knights game is just classic Piakura, nice hole running try, misses a simple tackle five minutes later and you're back to wondering how and why.
