  4. Any suggestions on how to stop the wing t with this D? Very interested in installing this next year and we see the wing t atleast twice a year. thanks

  5. Click on the link above for This Site: 4-2-5 vs the Flexbone - Secondary Play. You can rotate the safeties the same way as you do vs the flexbone. I would probably adapt the 4-2-5 to play an Under front with it, but that's just my personal preference.

    1. Coach, stick as closely as you can to the TCU system. Don't try and adapt pieces of the 4-2-5, take the whole thing. Use the TCU playbook link on this site, print it out, and read every word of it. Then use the great information posted here by Coach Hoover and others to learn how they have adjusted to things they see that the TCU playbook may not cover. We recently switch from a 3-4 to the TCU 4-2-5 and won a state championship scoring more points on defense than we gave up!

  8. John, the only thing about the resources is that they are not more streamlined into one playbook that tells you how to install everything. Really, you need to know just about everything from all the links provided. Start with how you will call strength, front stunts, LB reads, how to "undivorce" the front and coverage if needed, determine how much of the blitz package to use and whether to include any Fire Zones with it, and to have at least a couple of coverage answers to match up vs Trips and any formations you will see. I am pressed a bit for time these days but I MAY be able to write something up to help out this install process this off-season. Brophy, RunCOD, Duece, and others do a pretty good job of explaining and simplifying Patterson's defensive concepts. There's not really a shortcut, make sure you know it all to start with so you can smartly choose what and how much of the TCU system you need.

  9. Can this work vs. the Read Option or S-Option

  10. Certainly, click Duece's link (2nd from the top right now) on "Some More Stunts for the Zone Read" for more info.

  11. Coach Hoover,

    Thanks for all the information you have provided about the 4-2-5. I really like what this defense has to offer. I do have a question though, how does the 4-2-5 defend against the counter because it seems with the LB reads that it would be susceptible to the counter? Do you have any experience having to stop the counter with the 4-2-5? In addition, what is the most effective way to teach the LB reads? Thanks for the help.

    Coach C

  12. Coach C, very good question. Check out the very last link, the Pat Fox notes, which explains how I like to teach the LB reads in the 4-2-5. In brief, the LBs will read their G-T area to the near back and make a "Pull" call when the G or T pulls for the other LB to widen a bit and stack behind the DE to their side.

  13. Coach, is there anything on here that could help me with covering quad bunch/stack. I have seen the 4x1 scheme but not how to cover the bunch/stack. Any suggestions?

  14. Coach, check out runcodhit's post on Defending Tight Bunch Formations. You could also check Roll or Cover 3 and walk a LB out to the Quads.
