What is the difference between a flanker and a wide receiver?

A tight end lines up within the two yard zone at the end of the offensive line. The tight end normally is comparable in size to an offensive lineman but is an eligible pass receiver. In contrast, a wide receiver can be a split end or a wing back (depending on if he lines down on the line of scrimmage or not. A wide receiver is normally tall and skinny in comparison to an offensive lineman and is normally very fast.
