Luckily for him he has a good support system at home and with current Duke star Nolan Smith. The two share similar backgrounds, and the Blue Devil starter took a liking to Cook.
"That's my god brother," Cook said about Smith. "When we were young he just took me under his wing. He was 13 and I was nine and we went to a tournament together and were at the same hotel and he said I was his little brother."
But the relationship between the current college star and the sophomore standout goes deeper than that.
"He's helped me a lot," Cook said. "Me and him have basically had the same life. We both lost our fathers and we both have ambitious sisters and ambitious mothers, so he's helped me a lot."
Smith played for perennial AAU power DC Assault, so it should be no shock that Cook does as well. In fact on the 15's team this past spring, Cook made quite an impact on the squad.
As the starting lead guard, Cook showed why many think he's among the top point guards in the 2011 class. He's quick, tough, defends and is capable of getting into the lane to either score or create for others.
"I'm a pass first point guard," Cook insists. "I like to get everybody involved, but I'll shoot if I need to and I'm a lock down defender."
Following an impressive spring with the DC Assault program, Cook slightly tore the meniscus in his left knee, which forced him to the sidelines in late May and kept him out of action for the rest of the summer.
"The doctor said that I'd be back in two to four weeks, but my injury was all mental," Cook said. "I kept favoring it, so it took me a good four months to get back to my old self."
After rehab and weeks of working out the 6-foot-1, 180-pound guard hit the court and presumed his role of starting point guard for the Stags at DeMatha Catholic, where he plays alongside Josh Selby and Naji Hibbert.
"This year is going real good," he said. "We have a lot of highly recruited players on our team like Josh Selby, Naji Hibbert and Victor Oladipo. Playing with those guys is real fun and we are winning, so it's going good."
"I benefit from [playing with them] a lot because all of the pressure is on Josh and Naji and teams tend to sleep on me and Jerian [Grant] and they get all of the double teams and it leaves us wide open, so that helps us too," Cook continued.
Cook has helped DeMatha to a 11-1 record and is averaging 13 points and six assists a game.
Although a product of the 2011 class, the recruiting process has already begun for Cook. Among the schools that he's already hearing from are Maryland, Georgetown, Indiana, North Carolina State, North Carolina, Syracuse, Texas, Tennessee, Duke, Kansas State, Villanova, Xavier and George Mason.
"Since Georgetown is right down the street I go to a lot of Georgetown games and I'm real cool with their coaching staff," Cook said. "That's probably the school that I'm closest with right now."
Cook tried to set up a trip to tobacco road to visit N.C. State, UNC and Duke, but the trip was canceled because of a school activity. His plan is to visit the three schools once the high school season is over.
As far as an early commitment from Cook, don't expect it. He wants to wait out the process and enjoy it along the way.
"I'm seeing all of these guys committing early," Cook said. "I want to do the whole ‘He Got Game' thing where I wait until my senior year and there's some anticipation on where I'm going to go. I'm probably going to wait until my senior year. "
Cook and DeMatha will be back in action on Friday against Archbishop Carrol. Then they have a tough road ahead as their next five games are against the likes of Bishop Ireton, Bishop McNamara, Neumann Goretti, Gonzaga and Bishop O'Connell.
