Maybe it's a brave front or wishful thinking, but as good as the Heat have been, several GMs see them as far from

invincible when it comes to the postseason. The number one vulnerability is the fact that they rely on Ray Allen, Shane Battier and Udonis Haslem to play key roles, all 30-somethings who have slowed down considerably. That contributes to the second weak spot: their rebounding, dead last in the league last I checked. LeBron James' versatility has prevented those issues from being exploited during the regular season, but it has required a heavy dose of minutes and considerable energy from him. Give a team a series where they can scheme to attack those older legs and pound the Heat on the boards and it could be costly. "They can't afford to have long series' in the early going and I don't see them running the table," said one GM. This is not to downplay the Heat's terrific winning streak as much as to point out that inside the league regular-season domination isn't considered a harbinger for the post-season. How a team is built and weighing its strengths and weaknesses means more than streaks or records.
