This may be the only possibility, for being less difficult than trading Beal.
The only reason I don't really want to trade Booker is that he is the only player at all whom I feel the slightest connection to. One can find that odd, because I'm the one who complains about how Booker's "cool" personality is not conducive to winning. But having been drafted in 2015, Booker is the last remaining holdover from a Suns team with some players I actually liked. It's the same reason I felt a sentimental connection to Eric Bledsoe even though I wasn't a huge fan of Bledsoe. It's because of what Bledsoe represented to me. I was attached to the team Bledsoe helped anchor, and he was the last remaining key player from it, at the time the Suns traded him.
See my problem with Booker? His demeanor encourages me to feel distant from him, to feel that he is not really "my guy" even if I'd rather keep him. I'm not that attached to him, and if he were traded, I would feel sorry but would get over it. Same thing with Durant, but worse: I could care less about him. Or Beal, of course, or any player on this team. Put it this way: You want to stay cool, Devin Booker? Fine, I'll respond by staying cool too--toward you.
