Willie Cauley-Stein
The argument to start Willie Cauley-Stein is that he has earned it. After facing early struggles in his 2016-2017 campaign, Cauley-Stein had a gradual pattern of improvement once the season ended.
On defense, he remains to use his athleticism and length to give opponents trouble when defending them. On offense, he found his niche as he has expanded his game outside of the paint area, and as a result, he has been a better all-around offensive asset.
Last season, Cauley-Stein was the best center on the Kings, so if he continues to prove that going into training camp, he should be called upon to start on opening night.
