Don't know. I guess with CP3 on the roster the team can be sold more easily, but on the other hand: He obviously should be gone by now and will be gone next summer. So what kind of difference does it really make?
But in my eyes it's legitimate for the owners to veto, because they own the team. It's just that simple. So the Hornets will just lose their star next summer without getting anything unless the new owner arrives before the trade deadline and decides to deal him (to the Lakers
)
