Gareth Ellis has been superb in Super League for years now and gets better with every international series he plays in. He is a hard running second rower with the pace to go through a gap, the upper body strength to open a gap where there isn't one, and the hands to offload at the end of it. He can step a fullback with ease, his tackling is superb and he can play 80 minutes with little drop off in quality. And to top it all he will be in the prime of his career when he goes over to Australia.
Providing he doesn't suffer serious injury or loss of confidence this season I would say Wests have signed a player who would be up there with the very best second rowers in the NRL.
If I were a West Tigers fan, I would be very, very happy with the signing.
