I could see Sarver pushing for Bynum based on the way his contract is structured. Only half of it is guaranteed for this year, and it's not guaranteed at all next year. If Robert Sarver met with Jeff Hornacek to discuss Bynum's contract, you could describe both guys as "Horny".
Even if Bynum had DeMarcus Cousins' basketball ability, and the Cavs were looking to get rid of him for basically nothing, I'd still not want to make the trade. This team is thriving based on (among other things) its great chemistry. It's not at the level of the 2010 Suns (according to most people associated with that team, nothing comes close), but this team's success has so much to do with the simple fact that guys like each other, like playing with each other, and like playing for Horny. At best, because of the bond the players have formed as a unit, Bynum would simply become an outcast; at worst, his attitude might rub off on one or two players, the team loses a few games in a row (as is bound to happen to any team), and then that attitude sort of creeps through the locker room like a disease.
