I don't see Cumming getting picked ahead of Robey given Robey's bigger and a better kick. But, Cumming does have more games across two U18 SANFL seasons to judge him by (he's also been very consistent over that period) compared to a bolter like Robey who only came onto the scene for the Eastern Ranges in the U18 NAB League from round 12 onwards (mind you Robey was starring by the finals).
