Funny how some people think I'm selling McElroy short by comparing him to Pennington and others think it's wildly optimistic. I meant it as a compliment, by the way. I am a big Pennington fan.
And I'm not really going out on a limb or making a bold prediction. "Ceiling" doesn't mean "this is what he'll be", it means this is what the fundamentals suggest is the best-case scenario.
