We've spent much of the offseason discussing the roster moves that an NBA team operating over the first or second tax apron can and can't make, and why it makes sense for a front office to do its best to stay under one or both of those aprons if it's in position to do so.
So it came as a bit of a surprise when one of the top free agents left on the market - Nassir Little - agreed to a contract with the Heat, who had been carrying 14 players on standard contracts and were operating approximately $1.64MM below the second apron line. After all, the expectation had been that Miami would stick with a 14-man roster to open the regular season in order to remain below the second apron -- a minimum-salary deal for Little (or any other player) would push them above that threshold.
Now, there are a couple points worth clarifying on Little's contract.
First, his one-year, minimum-salary deal is fully non-guaranteed, with Exhibit 9 language, Hoops Rumors has confirmed. That means that the forward's salary doesn't currently count against the salary cap, and if he's waived before the season begins, the Heat's cap situation will be right back where it was before the signing, about $1.64MM away from the second apron.
Even if Little makes the team, he'd be paid by the day during the season, so if he's waived in the first month or two, Miami would be stuck with only a partial cap hit and would be able to move back below the second apron.
The second point is more complex and it's the one we'll focus on at length today. Let's say the Heat decide they want to keep Little on their opening night roster, then he earns a regular rotation role in the first couple months of the season, making himself indispensable and forcing Miami to guarantee his full-season salary.
In that scenario, the Heat would go from operating under the second apron to operating approximately $449K over it. However, for the most part, their proximity to the apron wouldn't actually change the moves they can and can't make during the season in any material way.
