About as efficient as your spelling.
I don't know what to tell people who don't want ot believe. The data is there for your study. I presented as much on numerous occasions. Zeke is a product of our offensive line and his volume. I wish it wasn't true. That doesn't make it so.
Data and statistics only work if used correctly, and that is rarely done. I bet your study and data only look at the offensive line, yards after contact and so on.
Explain how your study and data account for the defense playing to stop the run, and how that compares to the data on other teams where the defense doesn't play to stop the run.
Show the correlation of teams who play to run, who play to pass, who have a mix, to how the defenses play to stop the run, pass, and both, and how that relates to the production of the rb's.
Show how the skill of the qb and receivers relate to the production of the RB's, and how zeke correlates with other teams.
I am sure you have looked at all facets to determine your conclusion.
Or you can watch him run, and notice he always falls forward, breaks contact, turns nothing into something, doesn't get hurt, can run, catch, and block.
I didn't want to give zeke another contract. I would have put it elsewhere, but he is really good.
