I really don't understand the origin and importance of the 40 yard time that everyone thinks is so special. How often does a linebacker on a given play run 40 yards (full speed as well). Ray Lewis's 40 time was 4.7 (maybe that's why he was like the 5th LB drafted that year after the likes of Reggie Brown who had exactly 0 tackles in the NFL). Perhaps a 10 yard burst speed might be helful in judging a linebacker. Well what about WR? They run 40 yards full out on a fly pattern. Well Darius Heywood Bey ran an incredible 4.30 and our own Hakeem Nicks ran amuch slower 4.49. How has that worked out for Oakland?
