You're right about overloads, they work very well Wellie. With regards to the Free Fire blitz, when you shift the line to the right, your NT should be lined up over the center, reblitz/stunt him so he takes on the center. You can then re-blitz/stunt, the DE next to him as well, but I don't think it will matter that much. Your OLB and MLB will charge the gap, and one is going to come through, usually it's the Mike.
If you shift and move guys around manually, blitzing is too effective and the OL is lost, '08 levels of lost. I had a guy run some retarded D, looked like one of those Nickel D's out of a 3-4 book, I couldn't get the ball off.
He would slightly move his LB's and the corners would come flying in off the edges. He was using the Dolphins, he switched his starting corners to a couple of rookies, I thought I would torch them. Both Davis and Smith(?) jammed my receivers at the line so well, even Owens was getting roughed up at the line. Checked their press ratings after the game, both were 90+. How the hell are two rookies rated so high in a category like that?
Can't wait until more of you pick up the game, sick of playing these guys who BnR, blitz every down, and move players around.
