MarShawn Lloyd

Lloyd has excellent speed, but he's had difficulty holding onto the football and staying healthy. He didn't endear himself to the Packers' staff during his first two seasons. 

While analysts who value athletic ability more than positional skills will see Chris Brooks as a minor obstacle to overcome, Brooks is a legitimate three-down back with power, contact balance, and vision. He's also reliable as a receiver and with ball security. 

Lloyd must curb his tendencies to bounce plays outside that don't belong there. He must hold onto the ball. He must stay healthy. Those are three big issues, so don't expect an easy leapfrog up the depth chart this summer. 

If he does so in a true competition, Lloyd has starter upside but it won't be easy.
