Bobbin' and Weavin' achievement with 1 controller
How I unlocked Bobbin' and Weavin' was by using Light Heavyweight Rashad Evans against a newly created fighter with default stats on beginner. Simply hold down RB and press left, right, down, or up with the LS (left stick) against the created fighter when he swings. The trick here is to jab and then sway backwards, when you throw a jab with x, the CPU will almost always swing next. You only need to worry about swaying away from 3 punches in a row, if he kicks you this doesn't effect the strikes, just don't get punched. The created fighter's stats are so low and Evans is a extremely quick fighter you should be able to unlock this within a few tries with just one controller. If you notice Evans moving a lot slower simply hit start and rematch.
