Exactly what I'm implying. LOL
We don't even use a "strongside DE". There is no strong side versus a 5-man line.
SDE is archaic and applies to when football was played in a phone booth and teams used inline TE's.
I guess nobody notices that are DE's stay on the same side most of the time. Phillips was almost always a left DE.
As far as the RB alignment is concerned, if anything you would want a lighter, longer and faster guy lined-up to that side because that's where Inside Zone and Zone Read takes place. That's the DE who's often unblocked.
