Glossary of Terms and Abbreviations

 

These are to help you understand some of the terminology that I will use on the website. As I point out all over the website, the list does not cover everything.

 

  • Backer (for blocking rules) = nearest linebacker inside of you
  • Backside = the left or right side of the C, OPPOSITE of where the play is going
  • C = Center
  • Cutoff (for blocking rules) = area about eight to ten yards beyond the LOS where a run play is expected to hit downfield. A ST might go “to the cutoff” on Bucksweep looking to hit a defender downfield after his RB has made a cut. The cutoff block has the potential to pick up the last defender who can stop the RB from getting to the end zone.
  • Diveback = HB or WB aligned behind a Tackle and at the same depth as the FB
  • Down (for blocking rules) = refers to a defender aligned head up on the next offensive lineman inside you
  • EMLOS = End Man on the Line Of Scrimmage; usually refers to the TE or ST for HB/WB alignment
  • FB = Fullback; the ‘tailback” of the Wing-T, most often aligned directly behind the QB and C
  • Flat motion = pre-snap motion along the LOS, where the HB or WB squares his shoulders to the LOS after reaching the QB
  • Gap = the area from one offensive lineman’s nose to the nose of the next man inside him (used for blocking rules)
  • HB = Halfback, who is aligned either as a WB off of the Split Tackle, or as a diveback behind the ST and even with the FB
  • Jet motion = pre-snap, flat, sprint motion by the WB or HB
  • KP = Keep Pass
  • LOS = line of scrimmage
  • Midline – an imaginary line that runs from the football back through the FB, splitting the C, QB, and FB. It is used as a reference point, mostly by the QB and FB.
  • Playside = the left or right side of the C where the play is going
  • QB = Quarterback
  • Rocket motion = pre-snap, deep, sprint motion by the WB or HB
  • SE = Split End, often the wide receiver opposite the TE
  • SG = Split Guard, which is the Guard opposite the Tight End, which is to the Split End side
  • ST = Split Tackle, which is the Tackle opposite the Tight End, which is to the Split End side
  • TE = Tight End
  • TG = Tight Guard, which is the Guard to the Tight End side, opposite the Split End
  • TT = Tight Tackle, which is the Tackle to Tight End side, opposite the Split End
  • WB = Wingback; running back who is off of the line of scrimmage, aligned most often outside the TE, or Tackle, depending on the formation
  • XB = cross block
