STRONG POINTS Whitner is a very good athlete with the foot quickness, speed and explosiveness to make hard hits and plays all over the field. Is consistently aggressive when coming up the field in run support and makes hard, physical tackles. Moves through traffic easily and has the foot quickness and agility to avoid blocks well on the move. Reads and reacts to passes well -- closes fast to make hard hits on passes in front of him and can get out to the sideline to break up passes right as the ball arrives. Can cover tight ends all over the field well in tight man-to-man coverage -- can stay on the receiver's hip deep down the seam.
WEAKNESSES Obviously, Whitner's lack of size is the biggest weakness for him -- can be dragged for extra yards by big ball carriers, misses some tackles and will struggle to maintain durability in the NFL. Lack of size will also hinder his ability to play strong at the point of attack -- NFL lead blockers will be able to knock him backward and eliminate him from the play too easily. Despite being able to stay right on tight ends' hips in man-to-man coverage, lack of height hinders his ability to make plays on high passes to tall tight ends. While he does a decent job covering the slot receiver, he lacks the ability to be very good in tight man-to-man coverage against quick and explosive NFL slot receivers.
looks like a nickelback to me...but he'll be moved to safety.
