Soward doesnt seem to be in great form, getting carried by Hornby at the moment.
I think the Dragons more than any other top side rely on their forward pack being at the top of their game. Soward has a supurb kicking game but his passing and running games are average at best, he needs that time and space the very very good St George pack creates to be at his most effective. He loses a bit of that time/space and his kicking game suffers he doesnt, like some of the other halves around, have that running and passing game to fall back on (at least not to the same degree).
Boyd does an excellent job as a defensive fullback for the dragons, one of the safest around, but he just doesnt seem to have much awareness in attack, and it's very hard to teach awareness. Dragons desperately need a fullback who can run the good lines, hover on the inside or slot into a backline movement, and, bar a few bright spots, he doesnt seem to do this very effectively.
