I don't understand the hatred for the guy. He's an excellent coach. Is it the fact that his team is beating up on us now? But you are right, I will never forget how he brought USC back to prominence so he has built up a lot of good will with me.
People hate him because he is cocky, a good coach, and the antics on the sideline. It is the same reason non-49ers fans dislike Harbaugh. I have hated him since his second year at USC.
