Tim is one of my favs.
While he has effort and enthusiasm in spades, sadly he is just not quick enough for NRL.
Cross is boarderline in the speed deprtment, but is more consistent in defence and carries and extra 10kg.
Compared, Josh, Edwards, Tovo, Finn and others coming through, he just simply lacks the physical attributes.
I hope he goes on to be a great player, I would never question his training ethic or his commitment, but in this day and age, you have to pick and choose which up and coming props stay on your books.
