JACK Interior Linebacker (ILB) of the 3-4 formation, that plays in the weak side of the formation. Also known as Mo.   JAM PRESS The act of engaging a receiver on the line of scrimmage and slowing or disrupting his route, a.k.a. press or bump-and-run coverage.   JUKE A quick cut to elude or fake out a defender.   JUMBO An offensive package which includes two tight ends, a full back and a half back. Similar to heavy jumbo, in which either the half back or the fullback is replaced by another tight end. In a goal line formation, Miami package, often one or more of the "tight ends" is actually a linebacker (the New England Patriots used Mike Vrabel this way - he has 11 career regular season TDs) or offensive lineman. In the NFL, such a player must report in as an eligible receiver because a lineman or linebacker would not generally wear an eligible number.
