Normally, I don’t knock a reporter’s question, but it is silly to ask if Kobe is LeBron’s biggest rival. They have never been traditional rivals in any shape, form or fashion.
LeBron, when asked by Ahmad Rashad if Kobe is his biggest rival: "I would say Boston and Paul Pierce if I had to name just one guy"

Paul Pierce makes more sense because of the battles LeBron has had with Boston while in Cleveland and now Miami.
