The more depth in the forwards the better, U20's are unlikely to be able to cut a call up into the NRL consistently, especially props and 2nd rowers so we need plenty of depth to cover. The big men always take a few more years to develop.
Plus Cross has an air of aggression about him, he doesn't roll over which was our problem in the forwards early in the year. Imagine him running of a good inside ball from Choc. He might be getting on but the other forward we are signing is 18, and these days you can only afford to look forward 3 - 4 years anyway, since if you do well the price of your guys inflates and someone else will try and take them.
