While Simon certainly possesses terrific physical tools, it's his mental approach that sets him apart according to his Gamepoint AAU coach Sunny Deen.
"Justin is just a really laid back kid," Deen said. "He doesn't really experience a lot of highs and lows and I think that is reflected in how he plays the game.
"His top priorities going into a game are to control the flow, set up his teammates, play good defense and be an extension of the coach out there."
Simon is enjoying the recruiting process, but is also letting his skills increase his offer list.
"He is incredibly gratified by the attention he is receiving, but what is great about him is he lets his game do the talking and you see that by how his recruitment has gone," Deen said. "He had some smaller schools on him earlier, but now the big boys have come calling."
One of those big boys happens to be the top-ranked team in the country.
"Getting that offer from Arizona was huge," Deen said. "Everybody is looking up at them in the polls and when you think about it, Arizona has always been known as point guard university. The fact that Arizona thinks he's their kind of guy is obviously something we like a lot."
Given Simon's upside, the Wildcat coaching staff figures to be involved in his recruitment for however long it lasts.
"I can't say for sure when he will decide, but I would certainly imagine that it will be sometime next summer," Deen said. "The next 8-10 months will probably be pretty big, because teams now know how good he is and we can start looking at which schools will be the best for him and maybe at some point get some visits set up."
