The story of Dylan Walker since he has been at Manly:
2016 - bought as a centre, but played 5/8 due to Killer's reluctance to play in the halves. They finally swapped mid-season.
2017 - We got Blake Green and Walks was back to centre where he won the positional Dally M.
2018 - Missed the first 9 games after PM's XIII injury, but still played centre despite no Green. After Croker's injury he was back to 5/8 and still played there after his own injury (eye socket thanks to his fight with Curtis Scott) and Barrett wanting to play Hodkinson off the bench.
2019 - Again missed the start (stood down) and returned in the centres. Then after losing Elgey and Croker, along with Des being a bit reluctant to continue playing then rookie Cust, Walks was back to 5/8.
2020 - With Fainu stood down and Api let go, Croker was moved to backup dummy half. But with Des again reluctant to play Cust or drop either Parker or Suli (or Garrick or Jorge), Walks was again the 5/8 until his foot injuries killed his season.
2021 - Playing the unfamiliar role of fullback (only played once before this year - in 2016) because of Tom's injury 2 weeks out from the season start.
We've rarely let him settle in one position, let alone his best position. The one time we did ... he excelled.
A few points I would add
I believe Dylan was actually signed to play #6 (link from December 2015)
The biggest issue for me is that Walker has never been great while defending at centre. He always seemed to fire out of the line, miss his target, arm grab or a combination of all three.
This wasn't such a big issue in 2017 as we had a habit of simply scoring more points (mostly via Tom/Jake/DCE/Green, plus the support cast all being fit and firing) than we conceded. We ranked 4th for most points scored that season but 6th for most points conceded - the only teams conceding more points than us finished 12th-16th.
At least when Dylan defends at 5/8 there was always multiple people to help him in the middle of the field, and he does not have to make defensive decisions like centres do.
Fast forward to 2021 and he would offer a lot more than Suli or Parker in attack... but seeing how opposition teams currently use our right edge as a highway it doesn't really inspire much confidence that Dylan would do any better in that regard if he were placed there. But it is still a better option than him playing fullback.
So, he should play centre... but it has been 5 years and I just don't think we have ever got amazing value for money out of him.
