It seems that you might have had the problem with the 7D + 70-200 II before you dropped the lens - there would be no way to know if you hadn't shot with the combination. If it's in focus in the center and sharp there, I'm not sure that AF microadjustment will help, but it wouldn't hurt. One thing to try would be to use Live View and 10x and with the lens set to MF, manually focus in a region of the field which shows up as soft on the final image. Or just do that at several places around the image (but keep track of where you set the focus). Then check the resulting images on your computer - that should help determine if it's an AF problem or an optical problem.
