Worst Boston Celtics free agent signing No. 16: Enes Kanter
Enes Kanter’s first stint with the Celtics cost more, but it was during his second stint in 2021-22 that saw the center’s impact skew mostly negative. Kanter was always an efficient scoring big, and he provided that during the 2019-20 season, but by the time he re-signed last season, even that part of his game had disappeared.
Kanter’s defense was always a question mark, and his inability to stay in front of defenders only grew worse as he aged. What makes his signing a negative was the locker room drama with Ime Udoka that came to light after the coach’s suspension — drama that may have impacted the team’s chemistry during the first half of the 2021-22 season.
Worst Boston Celtics free agent signing No. 15: Jason Collins
Jason Collins’ career was already on the decline by the time the Celtics signed the seven-footer, but after being a starter for much of his career and even a spot-starter in Boston, it was clear Collins didn’t have much left in the tank.
Collins was not the Greg Stiemsma replacement the Cs thought they were bargaining for.
Worst Boston Celtics free agent signing No. 14: Troy Murphy
Troy Murphy only played 17 games in Boston, but during that time, the career 39% 3-point shooting big man shot a nearly single-digit percentage from beyond the arc during the 2010-11 season.
Murphy was able to get back on track with the Lakers the following season, driving home how disastrous his Celtics tenure was.
