With Newman coming back from injury, Raines growing in confidence, White getting a few games under his belt, P.Bowden becoming more of a JB type, Gas and Polak holding down key possitions and an injury free Moore and Thursfiled, there is plenty of scope to rotate JBowden in the middle.
JB's best position is off half back, but with the lack of midfield class, I think it's a great idea to give him longer stints in the middle.
