Offer each NBA team a mulligan for one offseason move, and it's not yet clear how most would utilize it. The Miami Heat, unfortunately, are an exception to that rule.
Give them a do-over, and they'd surely take back the subtraction of Haywood Highsmighth to clear a roster spot for Dru Smith. Maybe Miami felt like it just had to have Smith (and couldn't keep him on another two-way pact), but that was a clear miscalculation, particularly with Pelle Larsson being at the point where he'll need minutes even when this perimeter group is full-strength.
