Those types of numbers would be quite an accomplishment. One player, Richmond's Lawrence Sidbury (4th rd, Atlanta Falcons), accomplished that feat at last year's combine. Sidbury ran a 4.68 in the 40-yard dash and did 28 reps on the bench.
Of course Sidbury isn't 6-foot-6 and 290-pounds either. Dunlap's combination of size and speed are what make him our top defensive end prospect for 2010.
