These are the things about Madden that irk me the most. Receivers not working back to the ball against zones, DB's allowing WR's to get leverage on them on inside breaking routes, OL's running AWAY from the MLB they're supposed to be blocking, etc. They fix these problems with goofy, glitchy solutions like DB's doing the electric slide to magically intercept posts and slants, LB's that have 65" vertical leaps, and HB's that can break four tackles simultaneously.
Some people want an arcade game, and some people want a football sim, but most of us will play either one, and it's easier to make an arcade game.
