No offense but this is a bad graphic and full disclosure I am a big fan of the cover1 guys
categories 1-5 are all basically the same in that we know he gets the ball downfield at a high rate: that means TDs will be high, adot high, ypc high, and explosive play percentage (basically a deep reception) all high. It's not that meaningful. 1st down rate is similarly connected. The issue w Davis is that he doesn't do anything except catch the ball downfield that well, PLUS he's a dropper of catchable passes. That's not really wr2 material imo
