Rob played U20s for Victoria, NRC for the Rising and signed a full time deal for the Brumbies all as a schoolboy (first Vic schoolboy boy to sign a Pro contract as such as well possibly?) and if the rumours are true, Scott Johnson has already made contact, on the basis of a Scottish Grandparent.
Rookie of the year is a stretch too far IMO, there's Koirobete, Meakes, Maddocks, Rona, Lomax, Simone and Perese who're all both "rookies" and likely to regularly feature in their teams best 23, but that's an impressive Resume for someone not turning 19 till September.
