Put on the film. Lynch gets off the ball faster. He hits the hole faster. He runs harder. He plays stronger. He shows better vision and he has better intangibles. There is a reason why he's rated higher. He's just a better player. Lynch plays faster than Irons. That’s’ what scouts mean by he doesn’t have great time speed. Lynch will likely adjust to the NFL better than Irons. Comparing the two is apples and oranges.
Timed speed is the 40-time, playing speed is the speed you perceive in games and on tape. Perceptions of playing speed are often wrong because different running styles can often make one guy look like he runs faster than another even though they run at the exact same speed.
For instance, on tape I got a feeling that Mike Walker, WR Central Florida was a 4.5 - 4.6 receiver, however his real speed was much faster than the perceived speed, he turned in a 4.35 40-time at the combine. This perception was a result of his running style.
There are indeed a difference between playing speed and timed speed, but a player with a 4.35 40-time doesn't have 4.5 - 4.6 playing speed.
The 40-time is an important indicator to a player's real speed.
Steve Smith out of USC was also perceived to be a lot slower than he really is, untill he ran at the combine.
Scouts didn't think Kenny Irons had great timed speed BEFORE he ran, however this has changed as he turned out to be a lot faster than most expected.
