Instead of just speculation on what a ST guy may do, here is some facts about what JL DID.
In answer to the pass coverage question I'll quote directly:
"He was also one of only two inside linebackers to play at least 75% of total defensive snaps and not allow a touchdown in coverage, despite dropping back on 50.8% of his defensive snaps last year."
As far as the chains moving on him, well I can't say I remember a whole lot of plays where that occurred. I'm sure he gave up some, but to say the chains moved on him every game? I'd have to see some actual facts on that first.
Meanwhile Ray Ray got a few penalties and looked fast on ST. I don't see it happening. He might split time with Dunbar. That's about it. And I can think of no way better to kill Ogletree's potential than to move him to the strong side so that Ray Ray can play weak. Why draft Ogletree at all then?
This seems more like the usual training camp high spirits where we (myself included) get caught up in what ifs. Kind of how Barret Jones gets talked about as a definite force on the line this year despite never actually stepping on the field. Maybe we should wait to see if Ray Ray does well in preseason before we get too excited.
