when he rolls out, no real blocking in front of him. sounds dangerous.
Not necessarily. Rolling Ben out doesn't automatically mean having the need for Roethlisberger to sprint out outside the tackles box. It's the depth that can work with the pass-protection working off the zone blocking scheme with Ben gaining depth in his dropbacks at certain angles and yardage, creating the most space possible between him and the line of scrimmage while still containing within the pocket. Different sets and combinations could work wonders if we can get Ben using his feet more to open things up downfield with mis-direction. If Heath was healthy, it would excite me more just thinking about it.
