He was pretty good - played for Vic country so he’s no hack.
College scholarships to the US run across a huge spectrum. You have Jack White playing at Duke ....great basketball program, great academics, an amazing life opportunity. Plenty of other Aussies are playing at North-West Bum**** State and getting neither good academics or basketball development/exposure.
There is footage of Gown playing in a touring team to the States against the youngest Ball brother - he could definitely hoop, but turning his back on the offer suggests it was more Bum**** State than Duke.
