If I was to do Williams, would you want the Manly game (playing out of position) or one where he played plenty of minutes in the middle against half decent opposition? Maybe Magic Round (38 minutes)?
You should also go back and read through the (shorter) one I did for Williams in round 1. He had some really poor moments in defence that game, but his ptb speed was next level. Maybe also the (longer) Chad one vs the Raiders, where Williams played really well and I called out a few really nice plays from him.
Personally I think Williams has his flaws and can get worked over a bit in defence, but is quite good at doing the little things that coaches love and fans don’t necessarily notice.
