Like, I'm not even sure Eddie would finish in the top 10 on 40-yard dash with this roster but he is a natural at navigating cluttered blocking and seemingly directing the tacklers right into one his blocking. Possibly, EJ wouldn't even be in the top 5 at DB on the 40 right now.
I'm of the mind that pure speed is more important for kick returns and tailback-like vision but applied to open field blocking is more important for punt returns. Saban was suggesting as much when he talked about the change to Eddie Jackson in this game. The fast guys were missing the blocking lanes that would've sprung them for a big gain, so he went with the guy who seemed to have a knack for weaving through his blockers for big gains on interceptions.
