I rewatched that Newcastle game recently where Rav brings the ball back and gets met by both Saifitis, Kurt Mann and Crossland (?). All 4 went in shoulder first and Rav hit them like a bowling ball scattering pins and knocked Mann out cold. Beautiful.
Rav weighs the same as Lawrie - 106kgs and could weather the storm in the forwards but you'd be worried about his defence. Sure he can hit but only if he's where he's supposed to be, not a good reader in defence old Rav. Taking some early hit ups though, he'd probably have more impact than Blake the fake.
