This is assuming the Heat will show up for the regular season. When all their key players except 1, are a year older, at an age when a year older makes a difference.
It should be a close regular season.
Plus, it's very possible Pistons win 55-60 considering they added nearly 10ppg to their starting lineup and 11 ppg to their bench at the guard position. They could mop up on the crap East teams and pile up some wins.
