I think we have a type of DE, as we prefer guys with height (see Trent Murphy, AJE, Rousseau, Darryl Johnson all 6'6" or taller) and it seems we like guys that can slide inside as well. So speed isn't as important as size is from these examples. I suppose we can see this as rarely do we see us get sacks when someone just beats a guy one on one with speed but instead coverage sacks.
