Porter's lone season at USC was a campaign of fits and starts. The 6-6 guard mainly came off the bench, but provided scoring when he was available. The Seattle native opened the season with five straight double-digit scoring games. Porter suffered a quadriceps contusion on Nov. 20 and ended up missing nine games. He returned on Jan. 10, but only scored five points. He was suspended three days later for "personal conduct issues." Porter would get his act together and return to the team on Jan. 24. He closed the season by scoring in double digits in five of his last eight games. The wing had a double-double with 11 points and 10 rebounds in the loss to Oregon State. He scored a season-high 17 points on 6-of-8 from the field in the Pac-12 Tournament loss to Washington. After the season, he declared for the 2019 draft and left with three seasons of eligibility.
