A primary source would be the video on Tik-Tok itself.
A secondary source is Libs of Tik Tok tweeting said video.
Sad a teacher does not understand basic sourcing.
You would be looking at each college RB who had two years of 1,400+ or 1 year of 1,800+ and a 40 time of 4.4 or lower, not every single RB to play in the NFL in modern times.
You need a group to compare your group to for your theory to stick.
I understand your criteria
The question is - What players with two years of 1,400+ or 1 year of 1,800+ and a 40 time of 4.4 or lower who play in an acceptable conference has a RAS score that does not fit your criteria?
The data from that question would isolate the parameter (RAS SCORE) you love so much to compare the two groups.
It is my theory that college RBs with incredible production contribute at the next level at a comparable rate regardless of their RAS score.
They all have high RAS scores. We know this.
How about the RBs who achieved the statistics you reference (not RAS scores) and how their careers turned out? It's more logical that a player who dominated in college will be better at the next level.
Saw that earlier.
One thing I noticed is the best PASS CATCHING RBs are not at the top of the list.
That's what we need most, yes?
A few notables off the top of my head I searched for there...
McCoy - 6.22
Kamara - 8.11
McCaffrey - 8.44
James White - 4.94
Kevin Faulk - 7.4
