I like Toa, but I see him as Wing/Fullback and backup Fullback at that.But Naden can play centre and adds strike,Toa and Tupou are young and with a better coaching side, will improve, Stains if not succesfull at fullback will be on one wing , or even centre. I made an error and said Talau, when i meant Tupou. But they are all young ,and thrown in the deep end, in a poor side. Toa and Tupou with the right coaching,and better side may surprise.
Coaches should hire against what they do best. I.e. Todd Payten is a Prop and he trains Props. Hiring Townsend was exactly what the Cows needed and Payten's weakness.
