The slot used to be a place to put your big possession receivers so that they could go out and find a soft spot in the zone of the defense and provide a nice, big target for your QB. Then Wes Welker came along and the paradigm shifted to finding little, quick guys that zip into and out of said soft spots in zone coverages. I think Greg Little combines both elements takes them to the next level.
Little was heavily recruited as a linebacker out of high school. But he went to UNC because they offered him the opportunity to be an athlete. He started as a running back and later shifted to wide receiver. So here you have in one package: a linebacker's mentality, a running back's ability (before and after the catch), and a receiver's skill. His frame is big enough that he can take a hand-off between the tackles and actually be the one dishing out the punishment on impact. His frame also allows for him to present a nice big target for your QB, and he's a menance after the catch. You also see in his highlight that he can be a viscious blocker in the running game.
He can line up in the slot and motion into the backfield to take a hand-off, immediately switching from 230 lbs receiver to 230 lbs back. He can be used effectively to run underneath, drag routes after guys like Keller and Edwards or Holmes run deep to clear out space. He can provide a big target in the middle of the field that Sanchez can trust to have the aggression and the athleticism to get the ball at its high point. He also can be used to crack down on a linebacker to create a crease in the running game.
Little would be a terror as a slot receiver for the Jets.
