Mansour could be one of the games elite wingers if he had speed, and was maybe 4 or 5 inches taller. He's so strong and powerful, busts tackles at will and gets through a mountain of work. But he's slow and it's hard to picture him scoring a length of the field try. If he did, it would be by breaking 13+ tackles and running over every player. Not by outrunning them. He also doesn't seem overly great in the air, and a few inches of extra height would make a huge difference I think.
The amazing thing is that despite how powerful and strong his leg drive is, he seems to be able to tiptoe around and be light on his feet too. Has scored some nice tries with no room down his sideline due to his upper body strength and some wonderful positioning of his feet.
If he keeps scoring tries, he might actually be able to hold out more naturally gifted players in James Roberts, Kevin Naiqama and Eto Nabouli for a spot. A winger making 15+ hitups and a heap of tackle breaks is valuable to the team even before you factor in the tries scored. Until late last year, he was pretty much just a workhorse without many tries in him. Then we got some decent centres and ball movement in our backline and he started scoring tries.
