This post is a continuation of a previous post on Understand BOB vs. the 3-4. The focus of this installment is on understanding the protection schemes that use a dual read by the OL in conjunction with a dual read by the back to help account for 7 potential rushers with only 6 blockers. Simple math makes it impossible for the offense to block all 7 rushers with only 6 blockers, therefore a 7 man pressure will still create a hot throw or a sack. The goal of this protection is to account for the most common 3-4 pressure schemes and allow the offense to throw drop back concepts without having to throw hot off of 5 man or 6 man pressures when the offense has enough blockers to account for those pressures. As in all Big on Big schemes the OL has the down linemen.
If both sides are danger the RB will protect the QB's blind side and the QB must be ready to throw hot.
