I get the point u are making but the base alignment of woody 3-4 is the 4tech. They may shade inside called a 4- but Thats head up the tackle. Not the guard. Most base 3-4 are 4 techs. I dont recall ever seeing a 3-4 where the base line is in a 2 0 2 technique which is called a bear front, really since 1985. The bear front is a well known front but not considered a base d and since the dolphins shredded it became situational. Woody will play this though so its a good observation just not our base front. A bear front is almost a 5-2.
With that said. One de will be as you say. 285. What remains to be seen is what he chooses to do with the other. Depending on personnel the 3-4 allows for a weakside de thats 255. In this alignment the olb typically will walk up on the strong side next to a 4- end. If he finds 3 starting bigger dl he likes, branch, glanton, cerge lets say. You will see far more balanced fronts with both olb being dynamic players. This is the scenario you refer too with two big de.
Imo we see one de being the 255 guy just because i think our best three dl are branch, amour, and one other. I think armour doesnt have enough range to play a true olb spot. So he stays in a 3pt.
The olb could be fun to watch though. Does he do a branch adams glanton or cerge line with armour at solb? Or no. I bet that could be one rotation though.
