I've been doing it for 6 years now.
We all have our own recipes for how we get to our numbers, I'm curious, anyone else here create a set?
I've long used a combination of returning offensive production/returning defensive production/, a few years ago I added OL experience/coaching evaluations/QB projections...
The obvious fault/hiccup are my coaching and QB projections. They are too subjective for my taste, nonetheless, I still use them because I am convinced a 2-3 year returning starting QB is much more valuable than a kid who hasn't started before. I recognize that Manziel is an outlier here, he is not the norm.
So, for those of you who create numbers, what variables do you focus on?
