Nafasi katika American football: ushambuliaji, ulinzi na special teams
Mwongozo wa majukumu makuu: quarterback, running backs, receivers, offensive line, defensive front, linebackers, secondary na special teams.
Ushambuliaji: quarterback, backs, receivers na line
Quarterback hupokea snap na kuongoza mashambulizi. Running backs hukimbia, kupokea na kulinda; wide receivers na tight ends ni malengo makuu ya pasi. Offensive line ina center, guards na tackles wanaolinda passer na kufungua njia za kukimbia.
Ulinzi: line, linebackers na secondary
Defensive linemen hupambana na blocks, kumshinikiza quarterback na kuzuia mbio. Linebackers hucheza nyuma yao dhidi ya mbio, pasi na blitz. Cornerbacks na safeties huunda secondary, kufunika receivers na kuzuia gains ndefu.
Special teams: kickers, punters na returners
Special teams hushughulikia kickoffs, punts, field goals, tries na returns. Majukumu ya wataalamu ni placekicker, punter, long snapper na kick au punt returner. Vikosi hivi huathiri field position na vinaweza kuunda nafasi za pointi moja kwa moja.
Nafasi ni majukumu, si formation moja isiyobadilika
Timu ina wachezaji 11 uwanjani, lakini mchanganyiko wa nafasi hubadilika kulingana na formation na hali. Offense inaweza kuongeza receivers au tight ends; defense inaweza kubadilisha 4-3, 3-4 na nickel packages. NFL na NCAA hutumia istilahi nyingi zinazofanana, lakini baadhi ya maelezo hutofautiana.
