Detroit Pistons forward Luke Kennard argued with a member of the Pistons' coaching staff on Thursday night, and it got to the point where teammates actually had to separate them.

Kennard had a rough night on Thursday, scoring five points on 1-of-8 shooting in a 112-102 loss to the Sacramento Kings. It has actually been a tough go in general for Kennard this season, as he is averaging just 7.2 points and 2.8 rebounds over 19.2 minutes per game. He's shooting 40.4 percent from the floor, 33.8 percent from three-point range, and 64.7 percent from the free-throw line in 22 games.

The 22-year-old, who played his collegiate basketball at Duke University, was originally selected by the Pistons in the first round (12th pick overall) of the 2017 NBA Draft. Kennard showed some flashes during his rookie campaign, playing in 73 contests and registering 7.6 points and 2.4 boards across 20 minutes a night while making 44.3 percent of his field-goal attempts, 41.5 percent of his long-distance tries and 85.5 percent of his free-throw attempts.

You can tell just by looking at the massive drop in his shooting percentages that Kennard has regressed this season, and his advanced statistics demonstrate the same reality. Of course, Kennard is still very young, so it is entirely possible he is just going through a sophomore slump. But the complete lack of any progression whatsoever is a bit concerning, especially when you take into account the fact that he is actually much worse thus far in his second year than he was during his rookie season.

The struggling Pistons fell to 17-23 with the loss to the Kings.
