Beverly is the new Matt Barnes - the younger, bulldog Matt Barnes, not the old, washed up (Laker) Matt Barnes. Clowns like that tend to wear on people's nerves fairly quickly, but every team needs one.
Westbrook is just misunderstood, IMO. He doesn't have any charisma to speak of, which leads to people not being able to read him well, which leads to him getting a whole lot of shit, which leads to him being angry.... et cetera. The few times he's shown off the court, he comes across as a relatively quiet, unassuming guy.
