No, there are still times when the OLB's responsibility is in coverage. Every time we aren't blitzing (rushing 4), we have an OLB in coverage: - In base, there are three DLs and one OLB pass rushing. - I rarely see Z in coverage, so mostly Preston or Gary. - In (some) nickel defenses, Z switches inside and Preston/Gary are the OLBs, so you have 2DL, Z, and one OLB in pass rush with one OLB in coverage. I'm not sure what percentage of snaps we play with those defenses (and there is a pass), but the most obvious pass defense is Gary, Z, Preston, and Clark pass rushing. So no OLB in in coverage for that situation of course. We typically have 3CBs, 1MLB, and 3 safeties at that point in coverage. I've not seen Preston on a WR - that obviously is to be avoided. His overall play has really elevated the last 4 weeks or so.
