"Obviously, Louisville is returning a preseason Top 10 team and for any freshman it will be hard to break into that lineup right away," Humphrey told InsideTheVille.com.
"But he loves to compete and won't back down from anyone. I feel confident he can defend right away and he can fill up. I think he'll fight for playing time next season as a freshman."
Knowles, considered one of the top three prospects in Kentucky, joins 6-8 Missouri forward George Goode and 7-0 Chicago, Ill. center Clarence Holloway in the Cardinals 2007 class.
Knowles averaged 21 points, 7 rebounds and made nearly 100 three-point goals as senior while shooting nearly 40 percent from beyond the arch. He led his high school team to the quarterfinals of the Kentucky State Tournament this season.
Prior to his official visit to Louisville this weekend, VCU was the clear-cut leader for the 6-1, 170 pound guard's services. That might not be the case for Knowles after returning from U of L late Saturday night.
"His visit went really well," said Scott Humphrey, Knowles' high school coach. "He went to check out Louisville and came back surprised how much he liked it up there. It couldn't have gone any better for both parties."
Humphrey confirmed that Knowles has a firm scholarship offer from Louisville. Humphrey said that he and Knowles plan to sit down Monday to talk about his pending college decision. "It's possible he could decide this week," said Humphrey.
"He's a little torn right now," said Humphrey. "He went to Louisville thinking he would go to VCU, but Louisville really turned his head. He played with the Louisville players on his visit and he really played well. We're going to sit down now and try to figure things out."
