| 释义 |
In American football, a spy is a defensive player assigned to cover an offensive backfield player man-to-man when they are expected to engage in a running play, but the offensive player does not run with the ball immediately. This strategy is generally used with "dual-threat" quarterbacks who may be expected to run on their own after expected passing plays break down, with the defensive player floating near the line of scrimmage, following the quarterback's movements.[1] Spies are also sometimes known as "keys".[2] Generally, spies are linebackers.[3] References1. ^{{cite web|title=Spying the Quarterback|url=https://www.sportingcharts.com/dictionary/nfl/spying-the-quarterback.aspx|website=Sporting Charts|accessdate=17 January 2017}} {{Gridiron football maneuvers}}{{American football strategy}}{{Americanfootball-stub}}2. ^{{cite web|url=http://www.footballoutsiders.com/info/glossary_general#s|website=Football Outsiders|title=Football Outsiders Glossary: General Football Terms|accessdate=17 January 2017}} 3. ^{{cite book|last1=Theismann|first1=Joe|title=The Complete Idiot's Guide to Football|date=2003|publisher=Penguin|isbn=0786548363|page=179}} 1 : American football terminology |
