Keep in mind, that for Lance to defend the 1 better than Hill, he'd basically have to become one of the two best point defenders in the league. While probably half the board doesn't appreciate Hill's defense because they don't understand how to defend the PnR, realize the rest of the NBA accurately recognizes Hill as one of the best point defenders in the NBA. (on top of that unlike fellow defensive stalwart Mike Conley, Hill can defend the 2, allowing PG to harass the 1).
