Sailor looks more of a full back to me. Kicking game is poor and not particularly creative but is quick. Lomax 2 years past it
I could see Saints experimenting with swapping Sailor and Welsby.Welsby is a better full back and half than Sailor, but Sailor looks to be better at full back than in the halves. I'd be letting Sailor use his pace and running game on kick returns and just joining the line wherever he sees gaps. Welsby seemed to be doing most of the kicking anyway even from the full back position.
