Not my discovery, but making the rounds on some forums is this small study done on the Football’s Future forums:

I have made a two-part criteria that potentially shows the correlation between the results of the 3-cone drill, the vert, and the broad jump in relations to a prospects ability to rush the passer at the next level. Obviously 1,2, or even 3 measured/timed drills cannot guarantee a success in this skill at the next level, but its very intriguing to look at.
To fit section A of this criteria a player must have been timed doing the 3-cone drill under 7 seconds. For section B, the player must have jumped a vertical of atleast 39” AND have done the broad jump over 10’00”.

The author then goes on to name players in the past who match these criteria and then later projects players who match this criteria in the current draft.
