I think some of the problem is something I have been complaining about since Garrett was here, which is those constant comeback routes. I do not mind comeback routes, but they run them so often and that helps the defensive backs so much both in defending the ball as well as tackling.
Teams like the Chiefs, Bengals, Rams, Packers, etc. have offenses that attack vertically. Again, vertically does not always mean 20+ yards down the field, but rather throwing and completing passes with the receiver headed toward the endzone either directly or via slant.
When you are known for attacking vertically, it makes the defensive backs more hesitant to jump comeback routes which means those few times you call a comeback route, your receiver not only has a few yards of buffer between himself and the defender, he also has a great chance to get several yards after the catch or possibly break for a long run.
