This post has some very good data compiled for receiver traits in which Nagy will likely be interested. He's focused mostly on the Combine data, which frankly has sold Kendall Wright short on his speed; factor in
his pro day numbers, even adjusted .04 on the 40 time to compensate for hand-timed measurements, and he comfortably hits the thresholds the author posits. I've warmed to the idea of bringing Wright back if it's not too expensive. (FWIW, I'm also with him on axing Markus Wheaton — don't let the door hit ya where Mother Nature split ya.)
I chose to make 2014 my cut-off point, which removed Jeremy Maclin and Da'Ron Brown from the data set, and then plugged the numbers into agility and twitch formulae I calculate every draft year to look for additional trends. Along with the thresholds given for 40-time (4.51s), vertical jump (35.5 inches) and broad jump (10.0 ft), a 3-cone time of 7.00s or under appears to be important. The sole exception to that time was Chris Conley, whose 4.35 speed on a 6-2, 215 lb frame appears to have largely made up for his lack of quickness changing direction.
Cam Meredith, Kevin White (yeah, yeah, I know), Josh Bellamy, and Kendall Wright all meet or exceed each of the four data points; Dontrelle Inman falls short on both the jumps.
