Welcome to my first attempt at formal rookie rankings for the world to see! I have used a mix of metrics that seem to matter based on my research, mock draft projections and a sprinkling of film analysis (done by people better at it than me) to arrive at this list.  

I explain why I chose the stats I did in the linked article above. While career yards and dominator rating are solidified, we don’t have verified numbers on some metrics.  To rank these RBs pre-combine I had to make some assumptions on the 2 values below. 

Height-adjusted speed score (HaSS)

This is a metric that takes into account height, weight and forty time into a single number that can be compared across players. I landed on 92.6 as a cutoff but think of that as a general threshold. I don’t think 92.5 dooms a player who looks good elsewhere.

While official measurements will be taken at the combine I calculated whether I think each player will make that 92.6 cutoff based on listed ht/wt and a forty time of 4.59. The letter “P” means that player will probably hit the threshold and “M” stands for maybe. Since it is a subjective estimation at this point, I have put an asterisk by that metric.

Please, blog, may I have some more?
