NBA History: 5 Worst Boston Celtics players since 2010

#4 Tyler Zeller (2014-17)

Tyler Zeller spent three seasons in Boston

After being selected 17th overall in the 2012 NBA Draft, Tyler Zeller enjoyed an impressive debut season with the Cleveland Cavaliers and was named to the 2013 NBA All-Rookie Second Team. However, following an underwhelming second year, Zeller was sent to Boston in a three-team trade - and the 7ft center once again faded following a good start.

Zeller started 59 times during the 14-15 season, averaging 10.2 points and 5.7 rebounds, although after starting the 15-16 campaign slowly, he was moved to the bench after just three games. After being dropped, Zeller would start just five more games over two seasons, and his minutes and production continued to decline. His skillset became increasingly outdated in a league that was embracing small-ball.

#3 Mickaël Piétrus (2011-12)

Mickaël Piétrus had proved to be an above-average swingman during his early years in the league with the Golden State Warriors, although after agreeing to a $1.3 million deal with the Celtics in December 2011, Piétrus made little impact on a playoff-chasing team. Piétrus averaged 21.9 minutes over 42 appearances (6 starts), although the then 29-year-old posted his lowest points total (6.9) since his rookie year while also shooting an underwhelming 38% from the field.

Despite his reputation as a three-point specialist, Piétrus connected with just 33 percent of his attempts from beyond the arc during the regular season, and his accuracy plummeted to 22% over 20 appearances in the 2012 playoffs. Evidently, Piétrus' performances were a major disappointment, and the Celtics decided to target other wings during the 2012 offseason.
