Running is TOO EASY on All-Madden! Please Fix!!!

It's incredibly easy to run up the middle, even with pass blocking set to 0 and CPU tackling on 100. I've worked with all slider options and even at the most challenging settings, the offensive run blocking seems way overpowered. Plus, AI defense is really bad. I can literally call the same run play up the middle over and over and they often don't adjust.
