1. JaMychal Green
Of those found mentioned on this list, JaMychal Green is the player who seemingly has the highest upside from an on-court perspective.
A soon-to-be 10-year veteran, the tweener big has made a name for himself as being a hard-nosed frontcourt contributor who isn’t afraid to get down and dirty and can stroke it from distance when given the opportunity to do so.
A high-IQ offensive player and a switchable commodity on defense what with his 6-foot-9 frame and 7-foot-2 wingspan, the 33-year-old is coming off a solid 2022-23 campaign with the Warriors where he posted per-game averages of 6.4 points and 3.6 rebounds while shooting a highly efficient 54.0 percent from the floor and 37.8 percent from deep on 6.6 attempts per 100 possessions.
Impressively enough, despite his age, these numbers don’t significantly differ from his career averages of 7.7 points and 5.5 rebounds per game on 47.7 percent shooting from the field and 36.8 percent shooting from distance, meaning Green still showcases an ability to play at a close-to-peak form.
Even during Golden State’s latest postseason run, the big proved that he can still produce admirably when seeing limited action, as he went off for a whopping 15 points on 66.7 percent shooting from the field and 50.0 percent shooting from deep in a mere 12 minutes of play during their Game 2 blowout over the Los Angeles Lakers in the Western Conference Semifinals.
Assuming the Celtics wish to bring on someone who can not only fill a roster spot now created with the departure of Robert Williams but also fill out some of his vacated minutes within the rotation, Green could very well be the best option available in free agency for the front office to consider signing.
