Why didn't Briscoe play at centre against Wigan instead of Sutcliffe?

Yeah I do. He's pretty good in contact, and will only get stronger. Some of his defensive reads are not great at the moment, but I think some of that will come with experience.

Now that BJB is definitely leaving end of season it's time to stop cocking about with Briscoe. He should play every week and build up the understanding with Watkins. BJB should now be used as the reserve back, only getting a game when we have an injury to wings or FB (although personally speaking if he has the skill to play FB then he should be able to play centre).
Rotation serves no purpose now. Briscoe is a better winger, he should play if fit.

this

nailed it fella.

I agree with the additional caveat that he should be used to allow rest for backs too, certainly hall, hardaker and briscoe
