Maybe I value defense a lot higher than the rest of the board, but I'd rather have a PG that can defend and at least contribute on offense. Shots come and go, but defense remains constant. Nobody has off-defense nights, just off-shooting.
Brooks is better because he is a more natural scorer and a much better shooter. His great speed helps him a lot too. Dragic has better physical tools overall but his game is too wild and he is too unstable as a player.
