In todays NFL, unless you're getting consistant pressure, penetration up the middle and force the QB off his spot in the pocket, or out of the pocket or make him relase the ball before he wants too, no secondary can cover for 4 and 5 seconds in todays NFL..Giants, Seattle,Denver as did the ninties cowboys did that and won 3 Superbowls, Leon Lett never got a great deal of sacks but his penetration into the backfield disupted the running game and forced QB's out of the pocket only to be sack by others..For me this team for a decade has desperately needed a dominant inside presense for consistant pressure up the middle to be dominant and they just aren't there yet. Collins showed promise but injury has hampered him, Ward was traded for to help inside, Crawford is a jack of all trades, Taco has entering his second year, has problems staying on his feet, Irving has ben inconsistant and can't stay on the field suspension and injury, Gregory has been out of football for nearly two years, a lot of question marks along this defensive line going into this season, the only known exception is Lawrence who is top of the heap!
