Tyranitar without sandstream wouldn't be OU. His most popular set in fifth gen is a specially defensive set. What would you be using him for once that special bulk is gone? Stealth rock? Dragon dance with base 61 speed? Choice band when you can just use terrakion? He'd be UU in an instant if not for his precious sand...which is better than what I can say for ninetales and politoed. For the record, garchomp has no problem mangling ferrothorn with a sun boosted +2 fire fang. Can't do the calcs for the other two right now though.
