The tight end is one of the more unique positions in football considering all the unique things they are considered to do. Tight ends are often called pumped-up WRs that need to be able to run routes, catch passes, and separate consistently from coverage while acting as the team’s security blanket on possession downs and likely being a viable end zone threat. Tight ends also must be capable blockers, generating a push on the LOS in the run game while also being capable pass protectors if asked to stay and max protect for the QB.
The NFL has become more of a passing league the last decade with more teams opting for the talented pass catcher over the rugged big-bodied blocker at TE.
