Garland, Martin and co. have the potential to be good, but Rivers is something else. It's not often that a defender wins the Rising Star as convincingly as he did. Bizzell taught him well.
EDIT: I would consider Rivers to be Melbourne's "best player" (comparing positions: apples, oranges etc.).
If Garland and co. kick on then I would love to see Rivers or Martin have a run up forward.
