Toronto Raptors
You can never count out the Toronto Raptors and Masai Ujiri. Considering that a similar situation as this one resulted in the franchise’s first NBA championship in history, I wouldn’t put it past the Raptors to potentially explore this possibility.
The Raptors have good assets as well and could likely find a way to get a deal done that Houston would like. Of course, I’m not sure Toronto would be willing to give up everything considering what just happened with Kawhi Leonard last offseason.
A trio of Kyle Lowry, Harden, and Pascal Siakam would be enough to make a deep playoff run in the Eastern Conference at the very least. Plus, if Siakam continues to develop at the rate he has, there’s a good chance the Raptors would emerge as a favorite in the Eastern Conference.
