Thinking further on it, perhaps we could move Lomax to #6. It would still give us his running wide, away from the ruck and if Swift can be a star at #1 then our team will be better. That move will also give Lomax a better chance of making the England team, as full back is probably the hardest shirt to get hold of at the moment.
My reservations are two fold -
Lomax has been devastating at #1, would moving him to #6 lessen his contribution - it may possibly appear that way in attack, but perhaps only because you get more space at full back so its a tad easier to look good.
If he is played as a second receiver rather than in the 1st receiver scrum half role, then he should be able to contibrute to his usual high quality.
As the season rumbled on last year, Lomax's decision making in the defensive line was increasingly poor, culminating in some howlers against Warrington in our last game. This may well have been the culmination of a limited coaching hand, but it is the ony negetive I've ever really seen from lomax.
