Gamble has been so unlucky. Dropped inexplicably last year and then injured when we desperately needed someone to stabilize the halves. Comes out and has a screamer in the first trial, completely outplaying Cogger in every facet... then gets a niggle and is rested out of concern - only for Ponga and Sharpe to put on a clinic and make Cogger seem like the answer again.
Gamble should be the halfback, but my feeling is they will go with Cogger because they've now at least seen that the team can function properly with him there. It will be considered the "safe bet". All Gamble had to do was be on the park for that last trial and it would have cemented him and then some. Footy is cruel sometimes - to players and to fans.
