It depends who you consider to be a two guard. Are McCollum, Wade, Harden, Middleton, Batum, and Butler twos? There are only a handful of guys who are definitely two guards and definitely better: Klay, Redick, and DeRozan (although I question his true impact). However, if you count all the maybe-twos I listed, then there are a bunch of guys who are better than Bradley. Ultimately, he's top 10 or so at his position, and grades out even better if you were to limit the list to "pure" two guards.
