I think you overlooked the title of this and what Eberflus said about him being a premier pass rusher and we're going to use him that way. Eberflus uses blitzes less than most coaches, so I won't be surprised if we play Micah almost exclusively at end.
Now, he does do that best, but it's tough to ask him to hold up at 250 pounds to going up against offensive tackles down after down. Frankly, I'd play him at SLB on early downs and have him attack the run and pass (not drop into coverage much), even if that means dropping a lineman so we're only rushing four. I also think if we're going to rest him, it needs to be on downs where a run is more likely.
