It is riskier from the NCAA as follows:
The CBA rules limit teams to two Western players - no more. The two "western" players tend to be the stars on the squad. So, when a player gets a small injury (like Mudiay did - a 10 day strain) they may replace them quickly (like Mudiay got replaved Wil Bynum). Thereafter, there is no more tape on Mudiay and he was not playing competitively until the playoffs.
So, there are limited spaces for western players, you are competing with former NBA players and other rising stars for those limited spots and any injury is highly likely to result in being waived.
