My colleague Charles Davis has used the phrase "running back revolution" several times over the past 2 years to describe the tremendous influx of talent at the position in the 2016 and 2017 drafts. This year's group of RB prospects is just as impressive. I always believe it's helpful during the evaluation process to rank the current group of prospects among the players at the position from the previous two drafts. I recently looked up the grades I gave to the running backs in the '16 and '17 draft classes and I slotted them in with this year's crop of talent. Here's the order I have them in based on their draft grade.
