Brown is the primary target, Waite the secondary. On the other hand you can say one gets a better defender and doesn't get the chance to get as far up the gound as the other to get involved in the play.
One also has far less clangers, has more pressure acts and gets involved in more scoring chains.
I'm not saying that Wood should go first. Just that if we are happy with Wood's output is Waite really playing that poorly when he is having a more positive impact on games?
