Celtics Likely Looking Forward to Season Opener Against Ray Allen, Heat

It's no secret that the Celtics and the Heat have rapidly formed a rather heated rivalry over the past few years.

Miami has knocked Boston out of the playoffs in each of the last two seasons, doing so in particularly heart-breaking fashion this past season. And now, with Ray Allen's defection to South Beach, the rivalry is as intense as ever.

So, although the two teams may not admit it, it wouldn't be surprising if the Celtics already have the season opener at Miami circled on the calendar in anticipation of some revenge.
