Wide receiver Derrick Williams was drafted for his speed. In his rookie season a year ago, the Lions did not have super-high expectations. They thought he could maybe return kicks and then gradually become a wide receiver.

Williams struggled through his rookie season. He got off to a slow start due to an injury in training camp and never really caught up.

Expectations are higher for this training camp. If Williams is to become a regular with the Lions, he has to prove he wants it with a good showing at training camp.

The third-round pick out of Penn State, was highly recruited coming out of college. He has the speed and the hands. Now he has to figure how to put it all together to cobble together an NFL career.
