Did you happen to notice how bump and run is handled in 2005 when you broke down the game from IGN?
As in did you notice if the bump and run check is done per play or per player in 2005? one of the biggest gripes we all had in 2004 was that the check was done per play, therefore it was all or nothing when it came to whether or not the bump and run held up a receiver at the line. Having all 4 of your receivers jammed at the line just wasn't right or accurate.
I really couldn't tell how effective the bump and run coverages were simply because neither player used it much. I did notice the cornerbacks played certain routes better than they did a year ago. The problem with that game was that seemingly every pass atempt the user would try to manually pick the pass off with his DB which usually resulted in a big play for the other guy.
