So the release rating is what indicates how well they can get away from bump coverage? Makes sense. Ideally every team should have at least one WR with a high release rate then. I know when I play against good players in APF2K8 who employ Bump Coverage, I like to have a really good HB for flats / screens and a Bump Buster WR (especially true if my opponent is good at manual coverage).
North, I just reference APF2K8 because it's what I know best, that's all. It's pretty much my point of reference for all football related discussions, and ironically it's where I actually learned the concepts and strategies employed in football. I haven't played Madden online, so I don't know what does or does not work against human opponents, which is why I listed options that I thought should work and asked for clarification on whether they do or do not work. Playing against a human opponent is always different / more difficult than playing against the AI. What works against one may not work against the other, and vice versa at times.
