This kind of reminds me of wine connoisseurs. Yeah, it has the right bouquet and the right color, is tart and has a oaky after taste blah blah blah. But does it taste good? If I like the taste of a $2.00 bottle of wine better, then I don't care.
We can do a preliminary assessment and so what if it isn't accurate enough. The only way to be really accurate is using hindsight.
Grading the draft now is just a prediction of how you think the players will turn out. Given that it is just a prediction, we accept the limitations of guessing what the future holds.
Yes, waiting 3 years will give us a better and more accurate assessment, but to be 100% accurate, you have to wait until all the players drafted are actually retired. So 3 years isn't perfect either. But we accept those limitations in our enjoyment of the team.
It is as relevant as the Mocks, because it is fun to speculate. Which is half the fun of being a fan and half the reason we are even on this forum talking about the team.
I want to go out like my Grandpa did. Peacefully in his sleep.
Not screaming in terror like his passengers.
