Evan Fournier
Evan Fournier was originally acquired by Brad Stevens in a steal of a trade at the 2021 trade deadline. He would play half a season where he averaged 13 points, 3.3 rebounds, 3.1 rebounds, and 1.3 steals on 45% shooting overall including 46% from distance on nearly six attempts. In the 2021 playoffs, the French guard is most prominently remembered for standing up to Kevin Durant when the Boston Celtics went against the Brooklyn Nets.
Since his Celtics tenure his play started to trend downward in stints with the New York Knicks and Detroit Pistons. I will not dig into his stats too much because a career 37% three-point shooter on five attempts always holds value on a contending team.
The Cs need a legitimate sixth man and another stint with Beantown would revive the 31-year-old's career.
