I don't think there is any chance that he does, but I would in a second, for one reason. Howard has proved to be one of the most durable players in the NBA, while Griffin has already had significant knee injuries, and is one of the more reckless players in the league with the way he goes up for dunks, no matter who is undercutting him. IMO, Griffin's knees are ticking timebombs, and putting on a Clippers uniform just increases the chances of a career altering injury sooner rather than later.
Howard immediately makes them the best team in the league for as long as he and Paul are on the floor together. Can't pass on that.
