But I thought Harden was able to sign one after being traded to Houston

And there is this:

"If he didn't sign, however, the Pelicans would likely trade him rather than risk losing him for nothing in the summer of 2020. That would also allow Davis to potentially sign a supermax deal with his new team. Teams believing Davis would be willing to sign a long-term extension to stay with them would offer bigger packages to the Pelicans than teams where Davis staying would be unlikely."
