I don't mean to be negative toward anyone's "true 4.3" times, but according to various reports we have:
Hyatt 4.31
VJJ 4.33
Holiday 4.38
I think there is 1 more in the 4.3 range
If we really have 3 or 4 guys with on-field 4.3 speed, then we should have an NFL level speed WR corps.
Color me skeptical of all these times and how they translate to the field. I've heard similar things before as well - Byrd, Chandler, etc without much real-world return.
Meanwhile, JJ and Callaway were out there with 4.6 or whatever times murdering people. There is a lot more to football than track times.
