Nah i dont see anyone who isnt in the squad who would improve that defense. Id probably have Reyonlds instead of Greer, purely because Reyonlds is not away to start collecting his pension, but he wouldnt start. Hutton is as good a right back as we have, and Robertson is the first real left back we've had since Davie Roberston, or it seems like that. Forsyth is a good option to back up Roberston and Whitticker is about as good a back up on the right as we have. You could maybe argue Jack, but he isnt really a right back, he can just play there. It would be a waste for the team.
