PLAYER ANALYSIS
Intriguing conversion prospect who is moving from quarterback to cornerback in an effort to make it in the NFL. It will take time for Marshall to go from a position of decision-making, patience and processing to one of frenetic energy and high-end athleticism. Marshall flashed at cornerback during Senior Bowl practices and his size will interest NFL teams, but his top-end speed and individual workouts will determine whether he's an NFL cornerback or a name-brand former college quarterback.
