Murphy can kick goals although I wouldn't say he is good enough to be first choice. He'll generally kick more than he misses though.

Powell is a smart player, a traditional scrum half with a good kicking game, good passing to his left and right and also a very good defensive player. He's not the quickest but he's still got some good footwork and acceleration which makes him useful when running with the ball.

As for Murphy he's come a long way in the space of a year. Despite his dropped balls against Leeds in the playoffs I can't remember seeing him drop a catch while playing for the under 20's. He's very confident and backs himself to claim the difficult kicks which is exactly what you want from a fullback. He's a smart player, reads the game well in both defence and attack and his footwork is also very good.
The one thing that might stop him being a top player is he doesn't really have out and out pace. Good footwork and good acceleration but over longer distances he's certainly not the fastest.

He's going playing semi-pro and working in the mines.

Wigan make alot of money from players going on loan/DC.

I'm already there

Talking to one of the lads today and he was saying since there doing away with U20 s . That's leaving them turning to semi pro plus working in Oz which pays a lot more than what they would be getting over here anyway
