Well for starters, trading either player only makes sense if you receive a quality return. However, I do believe there is a chance one/both players get dealt.
For Serge Ibaka, I will cover this more in a later question, but getting off his deal might be harder than expected.
Regarding Delon Wright, next season he will still be on his rookie deal, meaning his contract will have little to no impact on the Raptors ability to bring back Fred VanVleet. However, with VanVleet as the team’s backup point guard, it is fair to question his need.
