What's going on man? Yeah that I-Form twins or any 2WR twin sets is a money play where you can gain some easy yards about 80 percent of the time. I don't even use those formations to run to the outside because the CPU can't stop it.. EA messed up when they tried to disquise the coverages by making the CB follower the WR to the other side of the field when the WR goes in motion or in 2WR twin sets leaving the other side of the field open for big gains if the edge gets sealed off.. I hope they figure something out for that on Madden 14.
How much gameclock/runoff are you playing with and what game speed are you using? Did you tweak the sliders before this game? That might be the reason for that offensive explosion if you did because the CPU usually plays like crap in that first game after tweaking the sliders..Post the exact set you are using so I can take a look at them and make sure you didn't mess up something..
Your lineman must not be that good if you only have that many pancakes. My lineman are always at least in the middle of the pack with pancakes compared to the rest of the league.. It will get better once you build them up..
