.....just as there are many names for the position there are also many ways to play it , depending on the style you play but a few general things to look for.......
Ability to give and take pass under pressure ,retain ball in contact.
Speed in realigning to start next phase,both offense and defense.
SUPPORT
Should he run on to the pass or take it still...enough movement onto the ball to interest defenders but still allow enough time for the centers to do their stuff.
Don't creep forwards.
The wider the strike point of the move the deeper he will take the ball.
Establish and organise the defense unit and bring it (the centers) up in defense and control the actions of the defensive group...call slide drift etc.....and then to tackle.
Ability to distribute the ball well , but knowing when to hold on and penetrate ,straighten.
Chose correct options ie when to kick , attack the bind , go himself .
Ability to kick with both feet to start , then , under pressure as well.Well combed hair.....
