And I may be mixing you up with someone else but on one of the threads we argued on, someone said "it's just a Nickel defense, we ran one last year." And that's what this whole thread was started to push back against, the implication that we're not doing anything different than what's already been done. If I wrongly attributed that to you, I'll own it. But I've been paying attention to what works against the RPO and this was the sort of scheme I wanted before we made any kind of hire.The 4-2-5 is called that for a reason. It means 4-DL; 2-Lbs; and 5-DBs. What personnel and how you attack out of that alignment is a different matter. You can add a 3rd CB or you can add a 3rd safety. As a previous poster mentioned you can even add a LB type player in at a saftety position. Either way it's still a 4-2-5 alignment. Each team's personnel situation along with the game situation will determine the personnel grouping and how the team will attack out of that formation.
