I don't know, but I do know that the difference you're talking about is not as close as you make it sound.
Fox is on pace for 10 goals and 46 points. ADA is on pace for 21 goals and 63 points.
That's double the amount of goals, and 37 percent more points --- because as your prorate out, the gap only increases. So a 10 point difference now is not necessarily a 10 point difference 30 games from now.
Additionally, I have ALWAYS been leery of assuming that numbers can only go up. I'm leery of that when facing a players sophomore season (as next year will be for Fox), and I'm leery of that as a constant and not a variable.
Yes, there are some players whose numbers go up. There are some players whose numbers go down. And there are quite a few players who come in with good numbers right off the bat, and more or less maintain those numbers for the next 10 years.
So yes, Fox could produce more. He could also produce less, especially next season. And he could quite possibly produce at roughly a 45-50 point, steady pace for the next decade. So in two of those scenarios, I'm getting less production than I am from ADA right now. And less production than I got from ADA to end last season.
So again, no, I don't like those odds.
And I still don't have a burning desire to make that decision now --- which is a key component for me.
Sure, we might have to make that decision someday, but that day doesn't need to be today. And that's why I don't see any point in going down that path.
