• Nickel Defense = Fast & Aggressive• Cross between a 4-4 and a 4-3• Easy adjustment to Formations /
Personnel• Gap Controlled Defense with easy
defined run fits.• Good Blitz Angles • Good angles to set the edge!• Allows us to run split coverage defense.• Allows us to get to a 4-4, 4-3, 3-3, & 3-4
with same personnel.
Why Play the 4-2-5?Why Play the 4-2-5?
• If “Speed WINS” then Design your defense for Speed = – Aggressive Corners = Safeties– Stiff Safeties = LB’s– Oversized LB’s = Ends– Oversized Ends = D Tackles– Biggest D-Lineman = Nose (your
anchor)
