Something happened to Miller the last two seasons in Minnesota and Washington. His shooting percentage remained high but his scoring fell off a cliff. He appears to have just stopped shooting, but his assists and rebounds didn't go up so I don't know what he was doing on the court.
I still think Miller would be have better off in Boston. He would have got more minutes and played a more natural role than as the kickstand to Bron and Wade's moped.
Of course, that means Danny wouldn't have traded for Jeff Green, so it worked out for the best in the end.
