Have you played football, honest question? If so you haven't played receiver.
Haha for this guy using his at best, JV-Varisty highschool experience at WR to defend a not very good argument to begin with. I'm sure your experience in highschool is exactly the same as what NFL wrs do. Good lord...lets not take into account the much more complicated defensive schemes, the much more athletic defenders etc etc. O-line buys the wrs extra time to beat their man or let extra long routes/plays develop.
