In the neo-modern CFL, the strong-side linebacker is a defensive back in a linebacker position, who will cover the fifth receiver in the offensive formation, likely on the wide side of the field. Most often the SLB lines up on the side with the greater number of receivers, but may be tasked with covering a specific receiver and will follow his assignment in the formation. Some teams/coaches use the terminology NICKEL or DIME linebacker for this position. Positional responsibilities are complex, vary by scheme implemented and I do not attempt to cover all possible roles for this position.
Traditionally, the linebacker who plays the strong-side (wide side of the field created when the ball is located on a hash mark) of the field.
