An oversized 6'7"? Check. Capable of averaging over 20 points a game over the course of a season? Yes indeed. On the brink of a breakout season? Potentially. Yet DeMar DeRozan has only nabbed himself an 83 rating, and is perhaps the most underrated player on this list. Maybe this has something to do with the fact that, despite being a shooting guard, DeRozan isn't the best of shooters. His career average of .270% from beyond the arc makes for pretty unimpressive reading - but Raptors fans will surely agree that DeMar makes up for this with his size, mobility, and sheer will to win.
