what does tight end position in football do
Tight end Because of the hybrid nature of the position, the tight end's role in any given offense depends on the tactical preferences and philosophy of the head coach. In some systems, the tight end will merely act as a sixth offensive lineman, rarely going out for passes. Other systems use the tight end primarily as a receiver, frequently taking advantage of the tight end's size to create mismatches in the defensive secondary. Many coaches will often have one tight end who specializes in blocking in running situations while using a tight end with better pass-catching skills in obvious passing situations.
Squad number (association football) Squad numbers are used in association football to identify and distinguish players that are on the field. Numbers were originally used to also indicate position, with starting players being assigned numbers 1–11, although these numbers often bear little or no significance in the modern game other than the players' favourite numbers and the numbers available. However, numbers 1–11 are often still worn by players of the previously associated position.[1]
