It is way, way too oversimplified to say that a 4-3 DE = 3-4 OLB. First of all, every defense is a little different and so there isn't always a 1:1 comparison, but there are some generalities that you can apply. Second of all (and in general), there are two 4-3 DE positions, which have different roles and responsibilities, and there are two 3-4 OLB positions, which also have different roles and responsibilities. It is true that weak side 4-3 DEs are thought to be the "swing guys," meaning that if they were on a 3-4 team they'd likely play the rush linebacker role. But you can't just say that a 4-3 DE = 3-4 OLB, because a strong side 4-3 DE is certainly not the same thing as a 3-4 drop linebacker. A strong side DE in a 4-3 is also a DE in a 3-4, and a drop LB in a 3-4 is used primarily in coverage most of the time.
And lastly, not even all weak side 4-3 DEs can just easily transition to the 3-4 rush linebacker role. Some guys are natural with the switch, like Willie McGinest. DeMarcus Ware is another perfect example of a 4-3 DE moving to 3-4 rush LB. Others, like Dwight Freeney and Mario Williams aren't natural fits in a 3-4 scheme. Williams tried in Houston, and it was such a success that he went to Buffalo to get back into a 4-3 system. Freeney will also find a 4-3 team to play for next year, as his transition to 3-4 rush LB has only been slightly better than a disaster. I'd put Strahan in the same category as Williams and Freeney. I don't think we know nearly enough about AQM to say where he will be physically and skill set-wise when he is more fully developed as a player, and I know that was the original point here. But I think a lot of what you said (in a pretty condescending manner) isn't even totally true.
