Varejao and Hickson have 16 points apiece. LeBron has another 15. They've combined for 47 of Cleveland's 64 points. Edit: Make that 17 for Bron and 49 of 66 for that trio. Eight assists for LeBron too.
Shaq has another six points. The rest of the team has only 11 points and no other player has more than one basket.
Orlando, on the other hand, all five of their starters have scored between 7 and 9 points and Jason Williams is their high scorer with 10 points. Anderson has 6 and Pietrus 5. Very balanced scoring.
It will be more difficult for Cleveland to maintain their hot offensive play in the second half than Orlando. Two unlikely source of points (Varejao/Hickson) + little offense gained outside of them.
