To be fair to the Heat, Denver had nine days off, a period that started before the East champs had a chance to sweep Boston & earn 8 days off. Instead they travelled 3 times back and forth between Miami & Boston, though that is not the Nuggets problem. Now, they're no longer undefeated in the opening game of the series.
That being said, all things equal, I still think Denver would've won Game 1. It is also possible that the West Champs win each of the next 3 games, but I think it's too early to think it'll be a quick series. Especially with a couple home games on the other side of the country, and we'll see how Herro's return makes a difference.
Game 2 will tell us more in terms of how this series will play out, but IMO, I think Game 3 (or the first two games in South Beach) will forecast a better story. IIRC, Golden State ran over Cleveland 7 years ago including a steal of one of the Cavs first 2 home games.
Anyway, this series features teams I totally respect, so I'm hoping for a decent, competitive finals. The eventual winner will be one I'll be happy with, but I'll be saddened if it's over real quick
