It's not that easy. Back in Bob's day there wasn't as much competition for a gold medal. And everything was hand timed. Eye tests certainly don't mean much. The fastest official electronic times at the combine? 1 John Ross 4.22 2 Chris Johnson 4.24 And even the combine's official times since 1999 are only "partially electronic". Does make for an interesting conversation because there aren't clear answers...fastest player or fastest Cowboy.
