You will be setting off 5 seconds earlier and you will move approximately 25 mph faster. You should leave your contact lenses in the dressing room because unfortunately the physio's do not carry compact mirrors. You can't fail really but if you find yourself being overwhelmed by it all - just watch Matt King playing for Warrington and your confidence will bounce right back.

TROLL ALERT!!!!!!!!!!!!!

LOCK IT!

forget about ever trying to kick a RL ball.

most of your game is about running so youll need to learn to run the angles RL teams use in attack.

you will be making a lot more one on one tackles as well so that needs to pick up too.

you will also need to learn how to do a PTB, thats a fairly important part of RL, but dont worry after years of playing the game loads of RL forwards still cant do it properly.

where and who did you play union for?
where have you started playing playing league?

Outside centre is pretty much the centre role in league whereas you tend to see the Inside centre role being played by second rowers on both sides in league.
From my experience at playing Outside, your defence should be good enough to play centre in leauge, jeeesus i felt exposed out there haha
But yerr to answer your question you'd simply play at centre, choosing which side you preferred, full backs are pretty similar tbh but without the kicking aspect. I find these days League fullbacks are playing more like Union F/B's.

P.s. In league you're going to have to learn to cut a decent angle

Just watch league

Is this Noble's Union target by any chance?
