It’s a definite movement over the past few years and NRL coaches are at fault.
However.
Centre is an extremely important position if you are fair dinkum and playing this game as it was meant to be played. 6 of the 13 immortals are centres.
These guys were not just brilliant attacking players, but they were excellent defenders as well.
A really good centre can make your halves and wingers function better, and they can aid the fullback with setting a defensive line.
They should be prioritised.
Personally I'd be putting my money into 1,6,7,9 instead of centres. These guys touch the ball a lot more and create the opportunities for centres to finish.
Not saying centres are unimportant, but I'd always take a gun half who can create a gap for an average centre than the other way around.
