I think the the issue goes back to these boards (maybe it was ourbombers?) in that everyone agreed that the Hall defense can work beautifully... when that defense is loaded with all star talent. I remember many many threads ripping apart Richie Hall because of the soft coverage.
Lawrence, Houston and Holm are far from all star level of talent. We also require constant pressure on the QB so that they can only quickly get the ball out for the 4 yard pass... otherwise if they have time to make a quick 2nd read our DB's are playing so far off that it's an easy 8 yard pass each time against us.
