I also noted that CHS Hooker E Craig was listed as #5 in the Juniors team. Interesting choice for a second rower. Craig struggled at times during Schools games, but his lineout throwing would have been a significant improvement had the Juniors employed him in that role, as he doesn't really come across as a Second Rower.
How a boy who is selected into Combined States for National Championships as a #2 manages to be selected as a Second Rower for Club Championships is beyond me. However given the whole U17 selection process, I am not surprised in the least.
After asking around, it seems Ed Craig was brought into the Sydney 17s side from the shadow players (as noted in your team list earlier in this thread Hugh J) for injured second rower Austin Black (Wests). Though not a second rower, they wanted Craig in the side and he was first cab off the rank on their shadow list, so figured at 6ft and 90+kg or so, he could fill the breach. (Based on info from other threads, he missed out on the extra SJRU 17s Saturday selection trial and trial game at Nth Syd Oval due to Aust. Schoolboys Combined States team commitments). Given he got selected in the NSW U17s side, agreeing to play second row seems to have paid off for him. Perhaps his size fits the larger NSW Schoolboys teams better at hooker (and he does throw very accurately and consistently), but the smaller SJRU teams he fits better at breakaway and even second row?!
Clearly he can play rugby, but nobody is sure where to put the lad. Looking back through programs and recollection of games: Selected as #8 for Eastwood U17 Reps but played at #7 in the tournament. Selected and played Syd v Country at #5 as injury fill-in (no idea what position he's earmarked for in NSW 17s). Selected and played as #2 for CHS 1sts, and Combined States. A true utility forward it seems. Clearly, he's happy to get a run in whatever position. Obviously, different coaches and selectors see different skills, and adaptability. I would think next years schoolboys and colts will sort out where his skills are best utilised.
