Portland went 3-0 on the week. In those 3 games Melo was 27 of 47 scoring 67 points, grabbing 23 rebounds, though dished out only 8 assists. He turned the ball over just 5 times.
Clearly not the most statistically deserving (Doncic among others), but given the feel good nature of it and the basically meaninglessness of that "award" I don't have any issues with Melo getting it.
