If anything close to 4.59 holds for Dubgey that is huge. If he throws well it gets him some serious looks. My guess is Bailey was a little quick in the clock.
That's great for Dungey, though pro day 40 times are generally off by roughly 0.05-0.1 seconds. But still, even worst case scenario that's still a sub 4.7 40 which is pretty good for him.
