39) Al Jefferson
Former NBA big man Al Jefferson was one of the more underrated offensive centers in the league during the 2000s and 2010s, thanks to his low post-game. Jefferson started his career in Boston but was included in the Kevin Garnett trade, which sent him to the Minnesota Timberwolves, where he broke out toward the end of the 2000s. At the start of the 2010s, he was still in Minnesota, putting up solid numbers.
Over the first six seasons of the decade with the Wolves, Utah Jazz, and Charlotte Hornets, he averaged 17.1 points and 9.2 rebounds. While he didn't make an all-star team during his career, he did make third-team All-NBA in 2013–14 by posting nearly 22 points and 11 boards a night.
His numbers began to drop afterward, however, putting up 16 and 8, then 12 and 6 over his final two seasons in Charlotte before ending his career as a backup for the Indiana Pacers in 2017-18. He may have flown under the radar throughout his career, but his decade-long averages of 16.1 points and 8.3 rebounds are impressive enough to make an appearance on this list.
