Defensive holding,

[ilyazhito]

Indeed, the H or L would probably have a better angle, maybe even the F or S, if their receiver cut inside. The B would be screened out because he is also in the middle, and because he might have taken over a deeper receiver.

In a 5-man crew, H, L, and/or B would be in the best position to provide input on defensive holding against a receiver in the middle of the field.
