In 1984, the NFL allowed defensive linemen and linebackers to wear jersey numbers in the 90-99 range, since more teams were making use of the 3-4 defense and thus were quickly exhausting numbers for linebackers, who previously were only allowed to wear numbers in the 50-59 range. Since 2010, defensive linemen are allowed to wear numbers 50-59; this is in part because of the interchangeability of linebackers and defensive ends (a defensive end in a 4-3 defense would be an outside linebacker in a 3-4).
A 4-3 defense is a defensive front that consists of 4 defensive linemen (typically two tackles and two ends) and 3 linebackers.
