Ryo Myaichi, Brad Jones, John Guidetti, Jos Hooiveld, Gerrard Tremmel, Gareth McAuley, Youssouf Mulumbu... All decent options. Some good options in the Championship too, like Hugo Rodallega.
Robertson was one of our best players whenever he actually played, but he was underused because he's too young for Bruce, especially after the autumn time when Bruce went into ultra defensive mode for the rest of the season. Figueroa was even picked ahead of him at one point.
He had a lot of injuries too, not sure if you have factored that in, plus the Scotland games so there was a fatigue issue like you get with all kids in his position
