NBA Free Agency 2020 - 5 Players Boston Celtics could sign to stop Giannis Antetokounmpo and Kevin Durant in the Eastern Conference

#3 Michael Kidd-Gilchrist

Los Angeles Clippers v Dallas Mavericks - Game Four

Although he is only effective on the court's defensive side, Michael Kidd-Gilchrist will be a very viable option for the Boston Celtics as he will be available for a minimum contract. He looked solid covering Kawhi Leonard in the first round for the Dallas Mavericks and could do the same job for the Boston Celtics on Giannis Antetokounmpo.

Boston Celtics' head coach Brad Stevens is a defensive mastermind and can use Michael Kidd-Gilchrist in the right manner.

#4 Derrick Jones Jr.

Indiana Pacers v Miami Heat

Derrick Jones Jr. was solid when called upon during the playoffs for the Miami Heat. Jones Jr. hasn’t shown he can be a role man and essentially play the five, and his limitations mean that he won't be able to find a core rotation role in the league.

This means that he could be available in the offseason. Jones Jr. is a smart cutter who dominates the glass and works hard. He will hit the NBA free agency, and the Boston Celtics will have the opportunity to nab a defensively stable and athletic player for a reasonable contract.

Derrick Jones Jr. is a disciplined player, and that could be key for the Boston Celtics if they face Giannis Antetokounmpo and the Milwaukee Bucks in the postseason.

#5 Treveon Graham

Minnesota Timberwolves v Los Angeles Lakers

Treveon Graham is a well-built 6-foot-6 guard who can handle point guards and most wings fairly well. Graham was actually starting in Minnesota earlier this year before being traded to Atlanta, who have too much depth to offer him much of a role.

Atlanta will probably pay his qualifying offer to give them matching rights, and they already have D'Andre Bembry. This means that the Boston Celtics can pounce on a player that might be available for less than his market value in NBA free agency.

Treveon Graham is a good point-of-attack defender who can mirror the ball well and contest shots. That could prove to be key against a strong athlete like Giannis Antetokounmpo.
