It's such a small sample, I wouldn't worry about it at all. If this continues for the full season and maybe into next, then I'd start worrying about it. I prefer to take the patient approach with players.
Case in point that I love bringing up is Malkin from a couple of seasons ago. I'm sure lots of people sold low on him. Those who either bought low or held onto him reaped the rewards last season. Not that I'm comparing Elliott to Malkin, just the comparing the slump situation.
