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

To me the most important attributes for a WR are in order of importance below:

1) Quickness (not to be confused with and way more important than straight line speed), to me cone/shuttle, burst times are much more significant than 40 times.
2) Ability to separate and create space from defender (or simply get open). Route running and upper body strength certainly a factor here.
3) Hands, catch ability....without 1 and 2, 3 is moot
4) Straight line speed (40 time)
5) Blocking ability

Actually your #3 should be the #1 because it doesn’t matter how wide open you get if you don’t catch the ball the rest is moot. Great hands can over come some of the separation issue. Like MT, a DB can be draped all over him but he catches the ball at an amazingly high rate even for the NFL.
