Francois on field play is pretty clearly superior in this case though. He had a ridiculous Jr season. And he has comparable offers. The only reason seems to be 247 gave Francois a laughably low initial rating.
I actually think 4.5 range is very good for a CB given these are laser-timed. Not elite, but still plenty fast.
Akeem Dent ran a 4.54 last year, just by comparison.
