Yes you need at least 3 quality players in your 1, 6, 7, and 9. BUT, without some decent weaponry up front and out wide your spine is limited. With blokes like Cotric and JAC coming in there is plenty of motivation for the young spine players to figure out when to use the right weapon at the right time. Think of our record setting run of wins and the 04 premiership, when Shifty had a shotgun on one side of him, Utai, who he used a number of times to great effect, and a thinking winger with incredible timing on the other, Hazem, who he combined with many times with kicks to the ingoal.
Flanagan and Burton have been given the weapons, and the Flange especially seems to me to be a thinking halfback who is going to be looking for ways to take advantage of JACs speed and Cotrics tackle breaking. If Avo can make the 1 shirt his, it will add to the attacking options, and JAC and Cotric will need to be in his ear letting him know what they want from him.
