After a sophomore season that was decent, but in his view not good enough, Marcus Carr returned home to Toronto to double down on his college basketball career. The 21-year-old junior at Minnesota worked out two to three times a day. He focused on diet and sleep. He practised meditation. Carr arrived back on campus in the fall a leaner and quicker version of himself, and the work clearly paid off -- he's emerged as one of the NCAA's top point guards this season. Carr's not the type to chronicle his work -- his social media presence is virtually non-existent -- so his off-season transformation might have taken some by surprise.
