I don't really see this as a positive. I have no doubt he'll dominate for Penrith and probably be in discussions for buy of the year next year.
It's all well and good to blame the players for not living up to the expectations, but it's a long list and sometimes you have to consider "maybe it's not them it's me". Sullivan, Bateman, Laurie, Peachey, Brooks, Talau, Liddle etc. all underperforming while they were here.
In fact, I think Sam Fainu is the first player to perform above expectations in years.
