"Might lack elite stopwatch speed, but plays fast and can pull away in the open field." This statement is made in the anaylsis of Cedric Peerman on NFL.com's scouting analysis.
Of course, a 4.45 might not seem elite, but so far he's tops for the day; ahead of Beanie Wells and Glenn Coffee and Donald Brown. Ian Johnson is right behind him at 4.46.
It is no Chris Johnson speed at HB, but much faster than two of top ranked RBs. If you look at their analyses, both get commented on for their "great acceleration".
The comparisons and the analysis are so convoluted, and this shows the over-obsession with speed. If a guy isn't really fast, he can accelerate. If a guy is faster, he doesn't have elite speed.
Experts and their semantics.
