What is the issue here? The QB moved toward the DE, really.
If you want to contain that guy AND move him away from the pocket, you're asking too much. But if you really think it should / can be done, I'd assume that is a strength + foundation issue.
Pass block gives a bonus to the blocking attribute on passing plays. That isn't a blocking issue.
The DE seems to push the LT backwards, actually the LT had some problems this game with these high strength/agility/speed ends. So seems like I need to improve on his pass blocking but not if that means getting shoved backwards. His majors are all at about 70 and eq is split between blocking and strength.
