305 baby! Tacoi Sumler ran a 4.24 40 at the Nike SPARQ Ratings Championships during the Nike 7ON tournament. Oh yeah, that was 4.24 official electric time! He's a only a senior in high school man, Christopher Columbus High in Miami to be exact.
Chris Johnson of the Titans has the NFL combine record with a 4.24 40. I had to tell y'all that just for reference purposes.
