Physical traits, speed, agility, explosiveness attributes of Top WRs (What's the formula?)

As I have been compiling this data, the one attribute that really jumps out to me is the Relative Body Size (RBS). Very few WRs with a RBS less than 2.70 do well when it comes to catching a high volume of receptions. Obviously these "smaller" guys are the faster/big play guys and I am only researching the guys who lead in receptions. Even then, I would more than likely want a guy who is above average in RBS for durability.

If I were to draft a WR and he checked all of the blocks for playing football and playing WR to include, work ethic, heart, route running, hands (use of and catching), blocking, etc. I would look for a guy who met as many of the average or better physical attributes. If he had a deficiency on one, then he would need to excel at another.

I do not think it is a coincidence that over the last 5 years the average hand size has went up to well over 9.5" as has the average catch rate %. In 2018 there was 27 WRs who had catch rate %'s over 70% and in 2013 there was 3 WR with catch rate %'s over 70%.
