Clark is a legit 4.50 guy. His greatest attribute right now is that he doesn't know enough to know he doesn't know ****. So it's 6'6", a 33" vertical, and ability so far.
But he did know enough to recognize AR changing his slant to a fade against King. And you know AR must love a kid that doesn't know how to play WR knew enough to run a route he changed at the line.
