Haywood isn't known for his offensive arsenal, recording one double-digit scoring season in nine years, but he's a 53% shooter who rarely steps outside of 10 feet from the basket. As such, Haywood would be well-suited alongside Landry and Thompson, who'd play to their strengths on the perimeter, while allowing Hawes to serve as a spread-the-floor backup.
Udonis Haslem: A Charles Oakley-esque enforcer, Haslem does "the dirty work" and impacts games outside of the box score. The 29-year-old also quietly put up the most efficient season of his career while coming off the bench for the Heat — 9.9 points (49% FG) and 8.1 rebounds in 29 minutes per game.
Although he's undersized for a power forward at 6'8", he plays hard one-on-one defense and ranked ninth at his position in defensive rebound rate (24.8) last year, two areas in which the Kings have glaring weaknesses. Re-signing Haslem is clearly not at the top of Miami's priority list this offseason, and he may end up being a prime, relatively affordable target for the Kings.
Jermaine O'Neal: While it may seem like a lifetime ago, O'Neal was putting up 20 points and 10 rebounds as recently as 2006-07 before being slowed down by injuries. While his dreadful playoff performance (4.2 points on 20% FG and a 2.4 PER) didn't help his free agent stock, he put up 13.6 points and 6.9 rebounds while shooting a career-high 53% from the field in 70 games during the regular season.
He also still averaged a respectable 1.4 blocks per game, which would've lead the Kings, and played stellar interior defense. It's debatable whether the 31-year-old O'Neal would be a sizable upgrade over the Kings' current crop of bigmen, but if he were to accept a short-term contract, he could provide a low-risk, efficient compliment to Tyreke Evans on both ends of the floor.
Tyson Chandler (Early Termination Option): Still only 27, Chandler has shown that he has the skills to be a legitimate defensive center without being an offensive liability — 11.8 points (62% FG), 11.7 rebounds, and 1.1 blocks with New Orleans in 2007-08. Athletic and mobile for a seven-footer, he's been one of the league's best finishers around the basket (playing alongside Chris Paul tends to helps).
Unfortunately, Chandler has also battled a variety of nagging toe, hip, and elbow injuries over the last two years, and was limited to only 22.8 minutes in 51 games last year with the Charlotte Bobcats. If he decides to opt out of the final year of his contract, in which he's owed a hefty $12.75 million, he'd be a high-risk, but potentially high-reward option to anchor the Kings in the middle.
