When you are inside the 20 you need a player who can exploit one on one match ups in a short amount of distance. Mike Wallace is great when he can stretch a defense but he isnt going to out muscle or out jump a defender in a short distance. And neither is Antonio Brown. Now I dont expect them to go get a Megatron but someone who can beat these 5 foot 10 corners in the air or be able to physically create seperation inside a tight area is a must.
WR Alshon Jeffrey (6 ft 4 230) may just be that guy.
