In the immediate moments after Marcus Smart's floater rolled off the front of the rim to seal the Kings' 100-99 victory and end Boston's 10-game win streak, Hield was shown booting the game ball multiple rows up into the stands.
He finished the contest with a season-best 35 points on 14-of-24 shooting, along with six rebounds, four steals, and two assists.
The former Oklahoma standout is averaging a team-high 19.7 points while connecting on 40.5% of his threes per game. He ranks near the top of the league in both 3-point attempts and makes.
Hield signed a four-year extension in October that could pay the 26-year-old up to $106 million if certain incentives and bonuses are met.
Sacramento owns a 5-7 record.
