Cool thanks Big Hungry. I actually use 4-2-5 base out of 3-3-5 split because I love 3-3-5 too much to switch. It's pretty much the same except that you have a LB at the one of the DE sides. However, I'm pretty limited in my 4-2-5 knowledge anyway. I just know A Gap blitz concepts out of 4-2-5 which you can replicate with 3-3-5 split using the exact same setups.
