We should ask Bolt. Why he doesn’t set the wr in 40 and settle all the speculation down.
I’'m not sure what did Tremble mean by quoting - From my stats, the fastest 40y i’ve seen fro all the 9.7 or under guys was never under 4.30. That obviously includes, Greene, Powell, Ben, who were excellent starters.
I have a very strong feeling Bolt will not be that explosive nor fast on grass, out of no blocks. Actually I don’t know anything about the NFL , but as far as I know the best in there run 40 sub 4.3 fat. Bolt should show us what he’s got testing himself under the conditions those guys do. From a bit different perspective Bolt may be far from being called the fastest in the world…
