Aside from the obvious of not wanting to play a game 7 on the road against a team with renewed sense of confidence if the Cavs were to win, I think it would serve the Celtics well to get some of that home-court dominance back. While the Celtics have played much better in the playoffs than the regular season, they still don't have that air of invincibility at home that they had two years ago. I think a wire-to-wire dominating performance to close it out at home would send notice to the Magic that they're not coming into Boston and winning.
