I wonder what is a better test of speed, the 40 or MPH?
Started delving into this, that new feature from Next Gen Stats is great btw.
My conclusion: if you are measuring long speed MPH is the best indicator and it seems fairly obvious when you look into the numbers. Typically almost every player is hitting their top speed at the end of the run, can't recall one who did not.
This does not mean MPH is better at 40+ yards, it's at minimum better at 30+ yards but sometimes as early as 20+ with respect to measuring deep speed.
Put another way that 20-30 yard area is a little grey with a lot of variance but the 40 yard time generally is a better measurement of how fast a player is from to zero to 20-30 yards and MPH is a better indicator of how fast a player is from 20-30 yards to end.
A few observations:
*Saw Bond catching a lot of flak yesterday for saying he'd beat Worthy's 40 time. Was obviously way off base but he actually came close to matching Worthy's MPH and was the only WR to go over 24 MPH this year and really was head and shoulders aboves the other WR's in this department. To put in perspective the gap between his ending MPH between the second fastest WR was the same gap between the second fastest WR and the eight fastest. I'm not a Bond guy, but he did nothing to disappoint with respect to showing the NFL he has elite deep speed.
*Tuten is an interesting study. Despite the great 40 at no yard marker is the fastest(these are done as 5, 10, 20, 30 and end). He tails off considerably after 30 yards and drops all the way to 7th fastest at the end. If you look at his testing he's elite in his jumps, short shuttle and running 30 yards or less. This all matches up to show he's got tremenous short area explosive abiltiy and speed. That's great of course, means more to me then pure long speed. But that 40 time is probably overrating him as somone the league will view as that guy to take it to the house from a distance. Not all saying he'd be graded low in that department, just saying several other RB's tested better and relative to his 40.
*Raheim Sanders is sort of the opposite of Tuten. 4.46 40 at his size is great for sure so nothing to sneeze at but he's starts off as one of the slowest RBs from 5 yards out and then starts picking up steam and by the 30 yard marker he's the second fastest RB and by the 40 yard market he's dusting everyone.
