Before the King City Classic began Thursday, Blackshear, Scout.com's 11th-ranked 2011 prospect, played a pick up basketball game against the new King of the Court in Miami.
"I guarded him for the whole game we played," Blackshear told InsideTheVille.com.
After Blackshear's game against King James, a report on SlamOnline.com surfaced that Blackshear, a 6'5 guard from Chicago, forced James into an air ball from the three-point line.
Blackshear, one of the top players at the Cleveland event, also scored on James.
"It was a dream to play against my favorite player," said Blackshear. "I scored on him twice. I gave him a little jive on one and then the next one I split the defense on him and went past him for a lay up."
"It was really cool because that's my favorite player," Blackshear added. "It's a dream just to play against him and to go up against him it was just fun."
Though Blackshear played through tendonitis in both knees, he still earned respect in Cleveland. Clark Francis of the Hoop Scoop ranked him the No. 2 shooting guard in camp.
"My coaches tell me to rest but I never do because I'm always in the gym," Blackshear said. "The [doctors] say it's [caused by] a lot of wear and tear from landing and stuff. It will eventually go away but I'm putting so much pressure on my legs that's it's not going away right now."
Blackshear plans to get a little rest this weekend. He said he is skipping an AAU event in his hometown this weekend to rest up for a busy July schedule that includes the Nike Peach Jam and tournaments in Las Vegas and Phoenix.
"I'm going to try and rest up and see how I feel for the Peach Jam," Blackshear said. "If I do go to Peach Jam I'm going to tell them I can't play a lot. Then we've got Vegas and Phoenix and come back home for another tournament in Chicago."
Blackshear thought about visiting Louisville after the NBA Top 100 Camp last month with another Chicago star, 6'10 PF/C Anthony Davis, but the two prospects never made it into town. Blackshear said he still hopes to convince Davis, a Top 5 prospect nationally, to visit the Cardinals with him.
"I never made it down because I've been having camps," Blackshear said. "I'd like to come down there with [Anthony Davis] and show him around the campus and dorm and show him how good of a school Louisville is."
Rick Pitino was in attendance for each of Blackshear's games at the King City Classic watching his future star compete against some of the best players in the country.
"I didn't talk to him this week but one of the players called me and told me he said I was playing good," Blackshear said. "So that's a good sign."
