I'd go with LJ. You can't panic this early. Minny's run D is great but their defense is suseptable. KC will get on track at home this week. If they score 3 TDs this week LJ should have at least one maybe two. He also is chipping in as a receiver with 10 catches so far this year.
I'd go with Edge agaist Baltimore as well. He'll get a lot work in a close game.
