Admittedly, this is not too bold. Rather, it is on the edge of bold but still completely in the realm of possibility. Cauley-Stein’s career high for rebounds in a season currently sits at seven per game which he set last season.
The year prior, he averaged only 4.5 rebounds per game. His improvement in that category from 2016-17 to 2017-18 shows he is capable of making sizeable leaps in his season averages.
WCS has never been the best rebounder around, and depending on the statistic you use to measure his rebounding success, he may not be the best on his team.
