Carmelo Anthony leads the Knicks in frequent-flier miles on this nightmare West Coast trip, but is almost last in shooting percentage. Perhaps Anthony will get a chance to improve that 7-of-27 Western ledger. He rejoined the reeling Knicks Friday, will try to practice Saturday and hasn’t ruled out giving it a go on national television against the mighty Clippers Sunday. The Knicks continue labeling Anthony as “questionable.’’ The smarter course of action may be to save him for Monday in Utah when the journey concludes and the Knicks have their best chance of avoiding the humiliation of an 0-5 trip.
