When people think of blocking in football, they almost exclusively think of the gigantic manbeasts that you and I call offensive linemen. Blocking is one of the most esoteric aspects of football. Few know a lot about it and most don't care to. The focus for the average fan is on the skill positions and what happens in the trenches is of lesser interest (unless it was our 2005 line.)
It is rare that one thinks of receivers in terms of blocking ability. Highlights of blocking are rare and receiver blocking highlights are rarer still. Every now and then though, a block is the spectacular part of a play. Check out Tyrone Prothro erasing any chance of the South Carolina defense catching up with Keith Brown.
