I played a level 25 guy last week (I used the Saints, and he used the Broncos) and he used a nano blitz that looked like it was a nickel 1-5-5 type defense, but he made some manual substitutions. The most notable was moving Brian Dawkins to CB and Champ to the safety spot. He bump and run covered and sent the house. He manually guarded my rb, so it was house blitz with bump and run coverage.
The thing about this blitz was how fast it came! I only had 1.5 seconds to make a read and get rid of the ball. I had to dink and dunk all game. I ended up losing but it was frustrating how effective his blitz was! Also his bump and run coverage was pretty nasty.
Anyway does anyone know what the nano set up is for the Nickel 1-5-5 defense? I think I know the set up but I'm not as effective. I'll share some of my nano's if you have some knowledge to share.
