Definitely pick him. He is a very quick and an exciting player. I thought I'd heard one or two of our experts, on this forum, begging for a more exciting team.
I agree with Jonathan Davies ... get your best players on the field ... positions are not that important in the modern game.
Of course though you need a fair balance of trundlers, runners & the clever ones.
I noticed that the most exciting player/best with ball in hand in Super League at the moment (Bevan French) had a very ordinary game in the horrible conditions last Saturday. I doubt he will be left out.
