A few weeks ago, I sat down with the great Peter Howard’s (@pahowdy) college market share database and created a set of filters for college production that had a better hit rate than selecting just 1st round NFL WRs. This time I intend to do the same but with running backs. I have seen a lot of chatter on the Twitter site about characteristics shared by fantasy RB1s. For instance I saw that most of them run under a 4.6 forty. However, looking at just the successful players doesn’t make that a helpful nugget. You see, if ALL NFL RBs mostly run under a 4.6, then the fact that the best ones do still doesn’t help us when selecting from a giant pool of players.
