Statistics show Mansour is by far the premier NSW eligible winger in the competition, lengths ahead of contenders Akuila Uate, James McManus and Nathan Merritt in key attacking areas.
While Morris is guaranteed to be on one wing for the Blues, it is understood Blues coach Laurie Daley is undecided whether to play a specialist winger or shift a fullback into the role.
But when it comes to the cheap metres that are so hard to come by in Origin, Mansour is the contender most likely to produce the goods for Daley.
In three games this year, he has scored four tries and is averaging eight tackle breaks per game, way ahead of Morris (3), Uate (2.25), Merritt (2) and McManus (1).
Mansour is also averaging 18.3 runs per match for 172.3 metres, also a long way in front of Morris (11.2 runs for 125.8 metres), Uate (13.75 runs for 125.3 metres), Merritt (7 runs for 57 metres) and McManus (12.25 runs for 100.3 metres).
The Penrith winger has been cruelled by injury the last couple of seasons and, in an ominous sign for opposition teams, he believes he is yet to show his true potential.
"To be honest, I don't think everyone's seen the best of me yet," Mansour said.
"I still have more to offer. It's still early in the competition and I've got a long way to go to prove myself. I just have to stay consistent, that's a big part of my game I have to work on.
"I think my yardage game has been pretty good the three games I have played this year and I've been pretty lucky to get over the line as well. Having the good halves that we have, I've been pretty fortunate playing off them. If we get more wins here as well, it makes a huge difference."
Soward, who described former teammates Morris and Jason Nightingale as two of the best wingers in the competition, believes Mansour has all the attributes to crack into the representative arena this year.
"He'll be in the City team, for sure," Soward said.
"If he keeps his form up, and keeps doing the little things the wingers do, he'll be there and who knows what else he can do? As far as breaking tackles, he's probably the best winger in the competition.
"I just like his enthusiasm. Looking outside in last year, he was always a handful the way he runs the ball. But the biggest thing I've seen from Josh this year is that he's willing to listen and takes things on board. Josh is playing good at the moment but a couple of good games doesn't make a career."
Panthers halfback Peter Wallace, who has also represented NSW, played a lot of football with quality backs at Brisbane and believes Mansour would not be out of place.
"He's exactly what you need," Wallace said.
"He's fit as, competes hard, runs hard and knows how to score a try. He's got all the attributes but probably the biggest challenge for him is doing it every week.
"He definitely wouldn't be out of place in a rep jumper. He's so strong, he can stand in tackles and can offload. He not only scores tries but does the hard yards at the other end as well."
