02Scheme fit
Ideal system

Isaiah Johnson is a physical press-man cornerback prospect, with the size and athleticism to excel in schemes that frequently use single-high safety coverage and ask their corners to lock down one side of the field.

Press-man CBBoundary CBOutside Cover 1 CB
Best role

Immediate special teams contributor with the potential to develop into a starting boundary cornerback by year two or three, excelling in press-man responsibility.

Wrong fit

Weak zone coverage schemes, as his fluidity and instincts in off-man and zone are underdeveloped.

A high-upside developmental corner who needs to be in a system that values physical corners and can afford him time to refine his technique and understanding of route concepts.
