Ere led the NBL scroing in 2009 with 26.0ppg, ahead of Penney (24.2ppg, Redhage 22.9ppg and Anstey 21.8ppg). That's the only season he won the NBL scoring title, so I assume that's the season concerned.
In that season, Ere was playing in 48 minute games and the 3 point line was closer in than now, I think. Nonetheless, he scored at a points per minute rate about 10% higher than Madgen did last season, as the NBL's leading scorer. However, Penney (in second place) scored fewer points per minute than did Madgen and that was the case again in the following season, when Penney won the scoring title with 24.1ppg.
So will individual scoring averages be higher - depends on how much time coaches will play their stars, more than anything else.
