I wouldn't write T Williams off.
That try he let Souths score off the downfield kick is perhaps the worst piece of back play I recall from Manly for the year or perhaps any year.
On the other hand the award-winning try against the Tigers showed exactly the tantalizing prospect that he is.
Unfortunately he so far seems one of those players that alternate between good/bad and that's not really acceptable at NRL level.
The laziness and general lack of football smarts continue to be a worry despite the obvious size and strength that make him such a prospect.
Still there is time for him to come good, but he will need work harder to be what I think he should be, an impact off-the-bench forward.
