That’s because the Heat had yet to sign Herro, the 13th overall pick in the 2019 NBA Draft. Until Herro was signed, the Heat could trade him instantly, but once he’s signed, they have to wait at least 30 days to do so.
The trade speculation will end for the time being, as the team announced Herro had signed his rookie contract on Wednesday.
The former Wildcat has appeared in five Summer League games with Miami, including the California Classic in Sacramento and NBA Summer League in Las Vegas, averaging 20.4 points, 4.8 rebounds, 4.0 assists, 1.60 steals and 29.3 minutes while shooting 39 percent from the field (32-of-82) and 96 percent from the foul line (24-of-25). Over those five games five, Herro has recorded a plus/minus +83, resulting in all wins.
The Heat know they may have a future star in Herro, so it would be wise to not include him in any trade talks, even for a player the caliber of Westbrook.
