In a decision most expected from the time he got on campus, Kevin Porter Jr. is officially one-and-done at USC.

Porter made the announcement Friday morning on Twitter.

"I want to thank Coach Enfield and the rest of the coaching staff for giving me the opportunity to play Division I basketball, believing [in] me and pushing me each and every day," Porter wrote. "To the Trojan Family, I love you guys and I'm going to miss you dearly. I couldn't imagine any other family to be a part of. To my brothers, I can write a whole novel of the memories we made this year."

Porter arrived at USC with incredible hype and expectations as a 5-star recruit. He had some flashes of his potential, but overall it was not the season most envisioned for the talented freshman.

Slowed through the first part of the season by injury and later suspended briefly for undisclosed reasons, the 6-foot-6, 218-pound guard ended up playing in 18 games with two starts and averaged 9.5 points and 4.2 rebounds per game.

His best game was actually his final one as he scored a season-high 17 points with 6 rebounds in USC's Pac-12 Tournament loss to Washington, playing a season-high 34 minutes.

Here's how the latest mock drafts project Porter's stock:

--SI.com's Jeremy Woo projects Porter going No. 9 overall to the New Orleans Pelicans, noting:

"Porter remains one of the most intriguing prospects in this class in the minds of many, and different organizations will have different levels of comfort taking a chance on him. At USC, we probably didn't get a full sense of what he could do, and injuries and suspension made it hard for him to get into a rhythm. Porter has maturing to do on and off the court, but his explosiveness, off-dribble creativity and playmaking potential are going to be worth the risk for somebody."

--Bleacher Report's Jonathan Wasserman projects Porter going No. 11 overall to the Charlotte Hornets, noting:

"The Charlotte Hornets will look past Kevin Porter Jr.'s lack of production and focus on his long-term potential, which has shown up in flashes throughout the season. … Porter's shot creation is what could set him apart and help him emerge as a potent scoring option who can generate his own offense in the half court. There are questions about his feel for impacting games, plus a mysterious team suspension earlier in the season. But Porter should wind up helping himself during workouts, which will mask his decision-making and highlight his tools, bounce and skill level."

--ESPN.com's Jonathan Givony projects Porter going No. 15 overall to the Detroit Pistons, noting:

"Porter will start getting looks as high as the middle of the lottery, but he has some questions to answer about his approach to the game during the pre-draft process. At this stage of the draft, the rewards likely outweigh the risks."

--The Sporting News' Chris Stone projects him going No. 22 overall to the Portland Trailblazers, noting:

"Portland seems to value having multiple playmakers on the floor at all times, and while Porter has been inconsistent this season, he can certainly create his own shot. The 18-yard-old excels at generating space for his jumper, in particular. He'll need to figure out additional ways to contribute to winning if he wants to be a valuable piece on a title contender."

--NBADraft.net projects him going No. 29 overall to the San Antonio Spurs:

As for USC, the Trojans are expected to have six freshmen and a grad transfer coming in to replenish the roster. The Trojans have the No. 2-ranked recruiting class overall, including 5-stars Isaiah Mobley and Onyeka Okongwu.
