I am starting to think that the reason that Pompey is kicking is because he is better at it than SJ.
I know SJ was rested from kicking another season with a quad injury.
But that does not automatically mean the same thinking applies now.
It may well be that with SJs sore leg they saw the opportunity to trial the guy that has been nailing more kicks at training this year.
Whatever is the case, Pompey is a great kicker and I can see that being enough to tip the scales with him holding a spot in the team.
