The considerable differences between cornerback and nickelback make it as if Watkins is adjusting to basically two positions in the Eagles' defense. The play calls at either position mean different things. Cornerbacks can find themselves on an island playing one-on-one against a receiver. Lining up in the slot there is some help from the linebackers when in zone defense and perhaps from a safety over the top when in man coverage. While playing on the inside, one can afford to be a bit more aggressive.
