Lamb still has 3 more years (including this one) of being available for NYC. He is the same age as Sione was when he played seniors, but he isn't the same sort of amazing athlete that Sione is. He has the best football brain we have seen in a very long time, but i'd rate his defense as a bit weak at under 20s level still, and a NSW cup prop like Vaivai would use him as a speed bump at this stage of his career. I'd love to see him do a full off season with firstgrade next year and then play some seniors, but not this year. Having said that, i was worried about him playing NYC last year, and he took to that like a duck to water.
