The Boston Celtics are consistently looking to bolster their roster, particularly on the wing, as they aim for another deep playoff run. Here are nine realistic trade possibilities that could help address their needs:

1. **Kyle Kuzma (Washington Wizards)**: Kuzma has developed into a versatile scorer and floor spacer. His ability to play both forward positions would provide the Celtics with added depth and scoring off the bench or a potential starting role alongside Jayson Tatum and Jaylen Brown.

2. **Mikal Bridges (Brooklyn Nets)**: Known for his elite perimeter defense and improving offensive game, Bridges would fit perfectly into the Celtics’ system. A trade that sends a combination of draft picks and a young player might entice the Nets to part with their rising star.

3. **Terrence Ross (Orlando Magic)**: Ross is a veteran shooter with playoff experience. His ability to stretch the floor would help open up driving lanes for Tatum and Brown. A trade involving a couple of second-round picks and a young prospect could be enough to land him.

4. **Tobias Harris (Philadelphia 76ers)**: Although Harris has a hefty contract, his scoring and versatility could make him a valuable asset for the Celtics. The Celtics might consider sending back a combination of players to make salaries match, possibly involving forwards like Grant Williams or Derrick White.

5. **Gary Trent Jr. (Toronto Raptors)**: Trent’s sharp shooting and ability to score off the dribble would provide an additional scoring threat on the wing. The Celtics could offer a package involving a mix of young talent and draft assets to make this deal happen.

6. **Jae Crowder (Phoenix Suns)**: A former Celtic, Crowder brings toughness and defensive prowess. He could provide the Celtics with experience and depth on the wing, especially in clutch playoff moments. A trade involving a second-round pick and a role player might entice the Suns to part with him.

7. **Josh Hart (Portland Trail Blazers)**: Hart is a strong defender and rebounding wing who can contribute on both ends of the floor. A trade for Hart might require a mix of young talent and picks, but his skills would be a great fit for what the Celtics need.

8. **Dorian Finney-Smith (Dallas Mavericks)**: Finney-Smith offers versatility and defense. His ability to guard multiple positions would be valuable for the Celtics, especially in switching schemes. The Celtics could trade a combination of expiring contracts and draft capital to acquire him.

9. **Michael Porter Jr. (Denver Nuggets)**: Although it may take a significant package to acquire the rising star, Porter’s scoring ability and size on the wing would elevate the Celtics’ offense. Engaging in discussions around key players and future picks could be a route to explore for the Celtics.

Each of these trade scenarios presents the opportunity for the Celtics to improve their wing depth, enhance their playoff prospects, and maintain a championship-contending roster.
