Jonathan Taylor cemented himself as a legitimate first-round prospect with a stunning 40 time Friday at the 2020 NFL Scouting Combine.

The former Wisconsin star logged an official time of 4.39 seconds, making him the fastest running back at the Combine.

His home-run speed was something he showed off on a regular basis as a Badger (like this). Yet seeing him post that time, it reminds you just how fast he is.
