NFL Draft Scout is starting to update the profiles with Combine data outside the Top 10 performers by position, the 10 yd splits for the OL are very fast compared to their 40 times. Mankins had a 1.85 10 yd split and a 5.06/40. Out of those Guards who ran similar or worse splits this year, none are even close to his 40. The two top Centers at the Combine who also project to Guard, Unger and Wood...Unger had a 1.78 10 yd split with a 5.28/40...Wood had a 1.68/5.19. I think the official Combine timer and the new track will take some adjustment...I can see why the Scouts and Coaches stick to their own watches.
The CBS site featuring NFL Draft Scout data is updating slower and doesn't have the splits for the 40.
