​Today in Boston Celtics history, in 2014, the storied ball club re-signed guard Avery Bradley to a four-year contract valued at $32 million, which was fully guaranteed and included no player or team options.Bradley was picked up by the Celtics as the 19th overall pick of the 2010 NBA Draft, following his collegiate career at the University of Texas. He remained with the team until the final season of that same contract. One of the last remaining players from the team’s previous era of contention, at the start of that final season with Boston, he was traded to the Detroit Pistons, along with draft assets, in exchange for small forward Marcus Morris Sr.AdvertisementAdvertisementAdvertisementBradley’s trade was necessitated by the signing of former Utah Jazz All-Star forward Gordon Hayward in the summer of 2017. He averaged 12.1 points, 3.1 rebounds, and 1.7 assists per game while with the team.It is also the anniversary of Abdel Nader signing a four-year, $6 million deal with Boston in 2017. Nader was also drafted by the Celtics, with the 58th pick of the 2016 NBA Draft, and would play one season with the team before being dealt to the Oklahoma City Thunder, in which he logged 3 points and 1.5 rebounds per contest.NEW YORK, NY – DECEMBER 21: Kristaps Porzingis #6 of the New York Knicks gets tangled with Abdel Nader #28 of the Boston Celtics in the third quarter during their game at Madison Square Garden on December 21, 2017 in New York City.

The Dallas native was signed as an undrafted free agent out of Missouri in 2013, and he recorded 3.1 points, 1.5 rebounds, and 1.9 assists per game. Demetrius Jackson was also waived today in 2017, having been drafted by the team in 2016 out of Notre Dame with the 45th overall pick.

An alum of New Mexico Highlands, he was traded to the team in exchange for the rights to Bob Cousy, who wished to play for the team he now coached (the Cincinnati Royals) as a publicity stunt. Boston still had his rights. Dinwiddie played just one season for the team, recording 4.9 points and 3.4 rebounds per game.Ex-Boston big man Lorenzo Williams shares the birthday with him, born in Ocala, Florida in 1969. Having turned 10-day contracts into a rest-of-season deal in 1993, Williams played 22 games with the franchise, logging 1.5 points and 2 boards per game.Mar 18, 2023; Salt Lake City, Utah, USA; Utah Jazz guard Talen Horton-Tucker (0) lays the ball up on Boston Celtics center Luke Korn
