Elton Brand is a large man by almost any standard. The Sixers' forward is 6-foot-9, 254 pounds. It's hard to make someone that big disappear.

That's what happened during the first four games of the Eastern Conference Semifinals against the Celtics. Without the benefit of smoke and mirrors, Brand all but vanished. He averaged just 16 minutes, 4.3 points and 2.8 rebounds over that span.

There are all sorts of theories about why that happened.
