SEABL import players in the past who have moved into the NBL have normally been recruited as role players & not big time scorers. I can't think of any SEABL import players who have averaged 20+ in the NBL. Players like Lowery & Cro Magnum man played for many years in the SEABL before going up.
Over the years there have been heaps of players who averaged 40+ a game but have never got a look in - Delaveaga, DJ, Catron, Nunnelly.
If Dusty was playing SEABL what would his numbers be?
Sure trial Redhage(plays same position as Dusty) or Hall, they could be good enough(no other NBL team thinks so..yet) but I would tend to get an import 5 man with good range or a 3 man import to counter Cat's loss.
