What position should I play in Rugby League?

Unlike union, scrums aren't really an issue so that's not an issue. From watching the game for 20 years (I only played union), you hear more and more coaches talk of a lack of specialisation other than hooker, halfback/scrumhalf and five-eighth/fly half, which means that players are more interchangeable than ever. A back row/lock forward position might be something to consider, or playing centre. You don't mention speed/pace which could make playing in the backs a challenge. My honest suggestion would be to find a club that will give you the best opportunity to try both positions (if nothing else, an interchange player who can play in the forwards AND potentially centre is quite valuable). Also, work on ball-in-hand (even as a prop this should have been a priority). Best of luck.
