Nope - that's merely the interperetation of a moron.
Let me ask you this - when Roy Williams moves up and plays close to the LOS will he be a 5th linebacker or a safety being used up closer to the line of scrimmage?
Sure, he will have duties similar to a LB, but he will also back up and play back at times ..... he will have a dual role.
Same goes for the OLB. He has a dual role. Sometimes on the line as a pass rusher, sometimes back in coverage.
The actual 3rd string DE doesn't do that - he is on the line ALL the time.
Hell, by your viewpoint Ware actually almost never plays OLB - he is just a DE and we play A 4-3 defense 80% of the time.
