"I can't wait," Drew said. "I've been working out every day and lifting twice a day with my trainer."
Drew, a six-foot-six guard, is currently 203 pounds, but SLU head coach Rick Majerus would like to see him at 210 by the time he gets on campus in June.
Eric Schork, the SLU strength and conditioning coach, was in contact with Drew's trainer to come up with a plan to keep him on track.
Aside from work in the weight room, he's also been getting ready for the college game.
"I'm working on staying low and my overall guard skills," Drew said. "[Majerus] wants me to play the two or the three, and so I'm working on my ballhandling and getting to the basket. I also need to be a better knockdown shooter."
Alongside returning starters Kwamain Mitchell and Mike McCall, Drew figures to get a lot of open looks on the perimeter.
In his spare time, he's been talking with the players and staff and said he keeps pretty constant communication with several guys on the team through texting and Twitter. That includes fellow signee Keith Carter, who will serve as the Billikens' future point guard.
"I talk to them a lot," Drew said of his future teammates. "We talk about basketball, but also about everything else that's going on like all friends do. I have a good relationship with them."
In just a few months, he'll be gunning for their spots on the hardwood, but insists that he's fine with having a competitive friendship on-and-off the court.
Instead of summer AAU basketball like he's been used to for as long as he can remember, he'll likely be sitting in a classroom and getting ahead on coursework to ease the transition into college life.
He said it "already hit me" when he stopped by IndyBall, a prominent tournament in Indianapolis this weekend to see his old team and friends.
One major potential change was averted recently as Majerus declined an offer to take the SMU position. Although Drew didn't speak to the staff directly, he didn't feel as though there was ever anything to fuss about.
"I wasn't worried," Drew said. "The SLU staff has always been good at communication when something is happening, and so I knew I would hear something. Coach [Jim] Crews is coming to visit my school tomorrow, so I'm sure I'll learn more then. It reassured me a lot to know he wasn't going anywhere because it means he has a strong commitment to the players and to the school.
Now that he is officially a Billiken, Drew has been busy chatting up one of his good friends.
"I'm in Jalen Coleman's ear a lot," Drew said of his standout freshman high school teammate. "That's like my little brother and we get along really well. If SLU keeps up the success, I'm definitely going to stay in his ear."
Coleman is among the top freshmen in the Midwest and holds offers from Indiana, Notre Dame, Purdue, among others.
For now, he's content to worry about success for himself and the current squad to see where a talented roster can take them in the Atlantic 10.
"I'm just so excited," Drew said. "This is the perfect time to come to Saint Louis. After what they did last year and bringing everyone but two people back, I'm ready to see what we can do [next year]."
