I'm quite fine, I just had to work so the reply was late. I understand that there isn't anything wrong with the Heat being a 60-22 team this season, especially after starting out 9-8.
Of those 8 games (1-7), 6 have been on the road. Road wins against top teams are hard to come by, which is why home court advantage is a huge deal in the NBA. 4 of the next 5 games against the teams you mentioned for the Heat will be at home, and how they perform in those games will be helpful in telling us how they stand.
The Heat have less home games overall than any of the teams you mentioned.
The Heat lead the NBA in defensive FG%, defensive 3pt FG%, and are third in defensive efficiency, all while being the best defensive rebounding team. More than anything, those stats are what the Heat will rely on come playoff time. Given their injuries (Miller, Haslem) and the time it has taken a revamped roster to gel the Heat are doing pretty well to hold the second seed in the toughest conference.
