The 6-10, 255-pounder averaged 14 points and eight rebounds last season for the Gators, which finished 28-5 last season and advanced to the state semi-finals, losing to eventual runner-up Cheyenne.
"He came away impressed," said the source.
However, the source told RaiderPower.com that Platt's favorite is USC, followed by Oregon and then Texas Tech. Arizona State and UNLV round out Platt's top five.
"He is close to his family and staying on the West Coast is important," said the source. "There also is an impression that playing Pac-10 ball would be higher profile than playing in Lubbock."
The source said Platt still "needs to prove that he can score with his back to the basket."
"He has disappeared in big games down in the paint when double-teamed," said the source. "His progress now has him scoring away from the hoop with range and also scoring in the post."
Yet, the source said Platt has shown tremendous improvement and continues to polish his skills, which is evidenced by last month's selection to the adidas Big-Time all-tournament team.
"He had a lot of baby fat (as a sophomore) and has turned his body totally around," said the source. "The kid has made giant strides from a doughboy to recruited kid. He has played with NBA players, including Shaq, in the summer for three years in Las Vegas. He would be a solid addition and he's not a rail thin 6'10 kid. He's got plenty of bulk on his frame."
The source said Platt, who plans to sign in November, will still visit Texas Tech in September, but indicated a West Coast school will likely land his commitment.
"Texas Tech is an alternative, UNLV is a last resort, if the Pac-10 schools fall by the wayside," said the source.
